An important disclaimer is at the bottom of this article.

An exhibition dedicated to the 50th anniversary of the Olympic victory of the Polytechnician, ten-time world record holder, and speed skater Evgeny Kulikov has opened at the SPbPU History Museum.

The opening date for the exhibition was suggested by the champion himself—on February 10, 1976, exactly 50 years ago, at the Winter Olympics in Innsbruck, Austria, Evgeny Kulikov, a student at the M. I. Kalinin Leningrad Polytechnic Institute, won the gold medal in the 500-meter race. At the ceremony at the Polytechnic Museum, Evgeny Nikolaevich recalled that even the time of his winter race and victory coincided with the exhibition opening—10 a.m. The event was especially symbolic because the Winter Olympics are currently taking place in Italy. However, Russian athletes are participating as neutrals. All the more precious were the memories of past sporting achievements shared by Evgeny Nikolaevich and other participants in the ceremony.

As the famous song "Heroes of Sports" goes: "We want to give all the records our resounding names." Evgeny Kulikov named ten! In 1975, he became the first speed skater in the world to run 500 meters in under 38 seconds (37.99) and set the first world record for the distance. For this, he was awarded the Oscar Mathiesen Prize as the "Best Speed Skater of the Year." He also won gold and silver Olympic medals (silver at the 1980 Lake Placid Olympics), a silver medal at the 1975 World Championships, a bronze medal at the 1977 World Championships, and 18 gold medals at the USSR and Leningrad Championships.

"Yevgeny Nikolayevich is our first Olympic champion. And, of course, his name is already etched in gold letters in the history of the Polytechnic University, meaning it will live on for centuries. And he will always be a role model for younger generations of a harmoniously developed individual, strong in spirit, body, and intellect," said SPbPU Rector Andrey Rudskoy at the exhibition opening.

Yuri Avdeev, a member of the Legislative Assembly of St. Petersburg and president of the city's Olympic Council, once again recalled Evgeny Kulikov's sporting achievements and his activities after retiring. From 1982 to 1984, Evgeny Nikolaevich coached the USSR national speed skating team. From 1985, he was involved in the development of short track speed skating. From 1994 to 1998, Evgeny Nikolaevich served as chairman of the St. Petersburg Committee for Physical Culture and Sports. Since 2001, he has been vice president and a member of the executive committee of the Russian Skating Union. From 2011 to 2015, he headed the St. Petersburg Speed Skating Federation.

At the exhibition opening, Yuri Avdeev presented Evgeny Kulikov with a Certificate of Gratitude from the Chairman of the Legislative Assembly of St. Petersburg.

"Yevgeny Nikolayevich is a legend. The victories he brought to Soviet sports are our pride. Thank you for your contribution to the development of physical education and sports. And a deep bow to the Polytechnic for perpetuating the achievements of this renowned athlete," added Igor Vasilyev, Head of the St. Petersburg Sports Facilities Management Directorate.

Another legend among the ceremony's honored guests was the renowned sports commentator Gennady Orlov. He told the following story: "I'm the only one here who witnessed Evgeny Kulikov win the silver medal in Lake Placid on February 14, 1980. I was commentating the race with Eric Heiden, the future five-time Olympic champion. The only hope of all the speed skaters was that Evgeny Kulikov, by then already the Olympic champion in Innsbruck, would give him a run for his money. And so they did. After the first turn, Evgeny had a breakdown. I immediately ran over to the commentary booth and called him a former champion, but Nikolai Ozerov corrected me: 'There are no former Olympic champions.'"

The exhibition opening was graced by the presence of the widow and daughter of Anatoly Yegorovich Pavlov, Evgeny Kulikov's coach. Also in attendance were Polytechnic graduates Sergei Startsev and Vladimir Geller, who, in fact, started this whole story. Fifty-five years ago, two students from the Leningrad Polytechnic's power engineering department came to Chita for summer vacation, where Evgeny Kulikov was serving in the SKA sports company of the Trans-Baikal Military District. They met him while playing football and invited him to the Polytechnic. Then a letter arrived from Leningrad addressed to the head of the Army Sports Club. He advised the young man not to pass up the offer. Evgeny submitted his application and left for Leningrad. He passed his exams, entered the Polytechnic, met a coach, began skating, and won competitions.

"My greatest achievements and awards came while I was studying at the Polytechnic," Evgeny Nikolaevich emphasized. "So, thank you to the university for the foundation it gave me and for the honor you bestow upon me today."

After cutting the symbolic ribbon, Evgeny Kulikov himself gave a tour of the museum for everyone who came. He introduced each exhibit, reminisced about competitions, and spoke warmly about his mother, his coach, and his family, who became like family to him.

At the end of the event, an autograph session took place.

An important disclaimer is at the bottom of this article.

Novosibirsk Region Governor Andrey Travnikov held his traditional meeting with graduate students and young scientists at the Vorozhtsov Novosibirsk Institute of Organic Chemistry SB RAS on the eve of Science Day on February 6. Participants included Alexander Zhukov, First Deputy Chairman of the State Duma of the Federal Assembly of the Russian Federation; Valentin Parmon, Vice President of the Russian Academy of Sciences, Chairman of the Siberian Branch of the Russian Academy of Sciences, Academician of the Russian Academy of Sciences; and Dmitry Pyshny, Rector of Novosibirsk State University and Corresponding Member of the Russian Academy of Sciences. More than 180 young scientists and graduate students attended the event. Those present were interested in a range of topical issues, including the development of scientific research, promoting the commercialization of scientific research results, financing of the region's scientific sector, ways to provide young scientists with housing, landscaping, developing the social sphere, and improving transport accessibility in the Novosibirsk Akademgorodok. Those present also had the opportunity to participate in a discussion aimed at strengthening interactions between scientific organizations, graduate students, and young scientists' councils.

Elena Bagryanskaya, Doctor of Physics and Mathematics and Director of the N.N. Vorozhtsov Novosibirsk Institute of Organic Chemistry, Siberian Branch of the Russian Academy of Sciences, delivered the welcoming speech. She explained that her institute is the leader in the number of youth laboratories—seven of the 21 laboratories operating at the institute hold this status. This was the reason for the choice of venue for the meeting.

"Our laboratories offer great opportunities to young people. If they work successfully first as undergraduates and then as graduate students, they will be able to realize their potential as researchers and build a scientific career," said Elena Bagryanskaya.

One of the most relevant and sought-after support measures implemented in the Novosibirsk Region is the creation of youth laboratories, which are funded, in part, by the regional budget. Maxim Mironov, PhD, head of the Youth Research Laboratory of Chemistry and Technology of Secondary Metabolites of Plants and Animals at the Novosibirsk Institute of Organic Chemistry (SB RAS), spoke about supporting young scientists using the example of a specific youth laboratory. His presentation focused on the implementation of the project "Development of Technologies for the Integrated Processing of Plant Raw Materials from Siberia and the Far East to Produce Products for the Medical, Agricultural, Food, and Cosmetic Industries."

Ekaterina Simonova, a research fellow at the Sobolev Institute of Geology and Mineralogy, Siberian Branch of the Russian Academy of Sciences and a candidate of geological and mineralogical sciences, discussed support measures for young scientists using regional grants from the Russian Science Foundation as an example.

NSU Rector, Corresponding Member of the Russian Academy of Sciences, and Doctor of Chemical Sciences Dmitry Pyshny spoke about the conditions created for young researchers at the university.

"Novosibirsk State University is one of the leading educational institutions in the country. Our graduates are well-known not only in Novosibirsk but throughout the country, as they form the core faculty of the SB RAS institutes. Currently, 8,700 students are enrolled at NSU, with approximately 2,000 graduating annually. The number of international students has increased sharply in recent years, currently exceeding 1,500. NSU employs approximately 3,000 faculty members. Importantly, approximately 80% of them are part-time, directly working at SB RAS institutes at the forefront of science. Our graduate program is vibrant, with over 500 specialists currently enrolled. Not only Russian but also international candidates successfully defend their PhD dissertations at our university, after which they become fully-fledged, highly qualified staff for the university," said Dmitry Pyshny.

The NSU rector also said that NSU students and graduate students actively use grant support for their projects. They are recipients of a scholarship from the President of the Russian Federation for graduate students conducting research in priority areas of scientific and technological progress, they receive grants from the Russian Science Foundation under the Presidential Program for scientific groups led by young scientists – candidates and doctors of science, and grants from the Russian Science Foundation under the Presidential Program of Research Projects for Young Scientists. Currently, young NSU scientists have received five regional grants for the following projects: “Development of new catalysts for the production of hydrogen from renewable raw materials”, “Microresonators of whispering gallery modes for creating elements of sensor systems”, “Development of pyroelectric photodetector technology”, “Research of a new crystal for creating radiation sources in the mid-IR range” and “Development of measuring techniques for diffraction research at SKIF stations”. There are 7 youth laboratories at NSU, created jointly with industrial partners: “Technological solutions for creating functional materials and devices for use in electronics”, “Development of computational libraries for processing and analysis of seismic data”, “New biomedical genetic engineering technologies based on adenovirus”, “Development of new effective algorithms for describing and interpreting multi-component multiphase flows during hydrocarbon production”, “Development of new photonic technologies and methods for processing sensory signals using machine learning methods for agricultural technological applications”, “Low-carbon chemical technologies for use in organic electronics”, “Axiological potential of Buddhism in the context of international relations of Russia with the countries of East Asia: history and modernity”.

Importantly, NSU has established dissertation councils. As part of its system for training highly qualified personnel, it operates a system for independently awarding academic degrees in such fields as mathematics and mechanics, physical sciences, earth sciences, economics, engineering (computer science), and chemistry.

In his speech, Valentin Parmon, Chairman of the Siberian Branch of the Russian Academy of Sciences, noted that personnel training is of particular importance for the development of science, and NSU is effectively fulfilling this task. NSU has been and remains a unique source of talent for the SB RAS.

An important part of the meeting included answers from Novosibirsk Region Governor Andrey Travnikov and First Deputy Chairman of the State Duma of the Federal Assembly of the Russian Federation Alexander Zhukov to questions from young scientists. They discussed issues such as promoting the commercialization of scientific research results, funding for the region's scientific sector, ways to provide housing for young scientists, social development, landscaping, and improving transportation accessibility to Novosibirsk's Akademgorodok.

"The federal center is currently doing quite a lot in support of young scientists. There's a whole system of grants and labs for young researchers. State support measures are in place at the federal and regional levels, and there are also separate regional programs. Of course, we'd like to see more. Young scientists today are concerned about housing. I think this problem will be addressed over time," said Alexander Zhukov.

He also noted that the tasks set by the Russian President are entirely achievable with young scientists like those at the Novosibirsk Akademgorodok, including those of technological leadership.

Novosibirsk Region Governor Andrei Travnikov emphasized that the Novosibirsk Region Government is interested in strengthening ties between government agencies and scientists.

"Akademgorodok is a multidisciplinary research center, and the Novosibirsk region's economy is highly diversified. It's difficult to prioritize, and that would be wrong—we're trying to develop across all sectors, leveraging the scientific and educational potential we inherited," he said.

Alexander Travnikov also added that a comfortable environment and developed infrastructure are essential for scientists to work effectively.

"I can assure you that, despite the temporary budget difficulties we're experiencing this year, not a single infrastructure project in Akademgorodok planned for 2026-2027, at either the regional or federal level, is being curtailed or even delayed. Construction of the second phase of the NSU campus will be completed on schedule. The regional project to build the second phase of Akadempark will proceed. Improvements to the park on Demakova Street will continue. A rather interesting and large-scale project to create Cherbuzy Square will begin this year. A children's music school in Akademgorodok will be opened this year, and we will begin implementing the Universitetskaya station construction project," the Governor said.

At the end of January, Polytechnic students took part in their traditional winter recreation program, which took place at two locations: the Kholomki Educational and Historical Reserve and the Polytechnic Educational and Sports Center in the village of Toksovo.

From January 25th to 29th, two sessions in Toksovo offered a rich program of active recreation organized by Super Kultorg. Students participated in quizzes, team competitions, and games, spent time outdoors, and got to know each other. The trip helped them take a break from the daily grind, recharge, and spend a few days in a friendly atmosphere.

From January 26th to 29th, a parallel session was held in Kholomki, a place traditionally associated with a true winter fairytale by students. Here, the students had the opportunity to escape the hustle and bustle of the city, socialize with friends, and try new activities. Participants skied and snowshoed, spent time in nature, and recharged their batteries for the upcoming semester.

Following the student shift, PROF's leadership and activists arrived in Kholomki. A two-day strategic session was held to identify the organization's development priorities. Team building activities helped unite the renewed team and build effective collaboration among members.

The trip not only provided an opportunity to discuss plans but also became an important step toward forming a cohesive team focused on developing the student community and launching new initiatives. The winter camps demonstrated that leisure and work can be harmoniously combined, uniting students and activists with a common goal: making university life even more interesting and comfortable.

Boris Zaitsev: The Fate and Works of a Poet of the Silver Age

Translation. Region: Russian Federation –

Source: Official website of the State –

An important disclaimer is at the bottom of this article.

Boris Zaitsev was born on February 8, 1881, in Oryol. His father was the director of the Moscow Goujon Metallurgical Plant. The boy spent most of his childhood on the family estate, alone with his family and nature, and often recalled these times as the best.

He received his initial education from governesses. At 13, he entered the Kaluga Realschule, from which, after graduating, he began studying in the chemistry department of the Moscow Technical School. However, Zaitsev did not complete his studies at the school—he was expelled in his first year for participating in student unrest.

Zaitsev attempted higher education twice more: once at the Mining Institute of St. Petersburg (1899–1901), and again at the Law Faculty of Moscow University (1902–1906). Boris never graduated from either institution, as he was exclusively interested in literature.

The literary path – with important acquaintances

Zaitsev began his writing career at the age of 17. In 1900, in Yalta, he met Chekhov, who "blessed" him to become a writer. A year later, he sent his first story, "An Uninteresting Story," to Anton Pavlovich and Vladimir Korolenko. His meeting with Leonid Andreyev and the "Sreda" circle also played a crucial role. There, in 1901, among talented contemporaries, he made his debut with the story "On the Road"—Andreyev published it in his magazine, "Courier." A year later, he began a long-standing friendship with another distinguished colleague, Ivan Bunin.

At the same time, Zaitsev became a member of the Moscow Literary and Artistic Circle. In 1906, he contributed to the publication of the magazine "Zori," which lasted for several months, and from 1907 onward, he was a full member of the Society of Lovers of Russian Literature and the Society of Periodical Press and Literary Workers. Between 1909 and 1911, his second and third books of short stories were published.

Before the revolution, in 1912, the stories "Blue Star" and "Agrafena," the novel "The Far Land," the play "The Lanins' Estate," and other works were published, which immediately attracted the interest of readers and were sold out.

Life during the Revolution and personal tragedies

In the summer of 1916, Zaitsev was mobilized and enrolled in the Aleksandrovsk Military School. In 1917, he published the brochure "A Conversation on the War." In March of that year, he was promoted to officer, but did not participate in combat due to poor health.

Boris Zaitsev was apolitical and found it extremely difficult to come to terms with the violence and destruction that was unfolding. It was happening all around him, and even within his own family—his nephew died in the February Revolution, and his stepson, a young officer, was executed on charges of involvement in the Denikin conspiracy. Zaitsev would later write:

"We didn't notice the clouds, though we unconsciously felt their weight. The barometer was low. Fatigue, dissipation, and lack of faith, both at the top and among the middle intelligentsia—the people remained silent, while destructiveness accumulated within them… It's hard to remember. We paid dearly, but that means we've accumulated enough sins. Revolution always comes with a price. There's no point in blaming the old Russia: it's better to look at ourselves. What kind of citizens were we, what kind of sons of Russia, of the Motherland?"

In 1921, he was elected chairman of the Moscow branch of the All-Russian Union of Writers, and at the same time, together with his colleagues, he founded the Writers' Bookshop, which helped them earn money. Boris Konstantinovich then joined the All-Russian Committee for Relief from Famine, for which he was arrested along with other members and spent several days in Lubyanka. In 1922, Zaitsev contracted typhus so severely that he hovered between life and death for 12 days. Having recovered somewhat from his illness, thanks to the intercession of Soviet leaders Lev Kamenev and Anatoly Lunacharsky, he received permission to travel abroad with his wife and daughter to improve their health. Having received a visa, he and his family traveled to Berlin. Zaitsev never returned to his homeland.

The Voice of "Quiet" Russia in Exile and Faith

In 1924, the writer moved permanently to Paris. Having retired from politics, he became one of the foremost guardians of the classical Russian tradition. He wrote novels about the fates of the Russian intelligentsia (The Golden Pattern, Strange Journey), fictional biographies of Ivan Turgenev, Vasily Zhukovsky, and Anton Chekhov, and essays from Italy, where he lived for a time.

The writer found strength to endure separation from his homeland in his faith. He worked on hagiographic portraits ("Alexei the Man of God," "St. Sergius of Radonezh," "Athos") and novels ("Gleb's Journey," "Memories," "The House in Passy").

A researcher of Zaitsev's work, Alexei Lyubomudrov, noted that only in exile, forever deprived of the opportunity to worship at holy places, did he comprehend their great spiritual significance and make mental pilgrimages to them in his essays.

Nobel Prize nominee and the last poet of the Silver Age

In 1962, at the age of 81, the writer was nominated for the Nobel Prize in Literature. Although he never received it, the event was a universal recognition of the talent of the "quiet" Parisian writer and a sign of respect for one of the oldest literary figures in exile.

Boris Konstantinovich lived to be 91, becoming one of the last representatives of the Silver Age, a witness to an entire era. Although he was not as widely known as his colleagues Anna Akhmatova, Boris Pasternak, and others, his work occupies a special place in literature. It reminds us of eternal values: harmony, humanity, and faith, becoming a source of peace of mind for the reader. "We are a drop of Russia… no matter how poor and disenfranchised we may be, we will never yield to anyone the highest values, which are the values of the spirit."

NSU scientists have created a nanoantenna sensor to detect a biomarker for early cancer diagnosis.

Translation. Region: Russian Federation –

Source: Novosibirsk State University –

An important disclaimer is at the bottom of this article.

A terahertz nanoantenna sensor for detecting the biomarker L-2-hydroxyglutarate was created by researchers at the Laboratory for Functional Diagnostics of Low-Dimensional Structures for Nanoelectronics at the Analytical and Technological Research Center "High Technologies and Nanostructured Materials." Faculty of Physics Novosibirsk State University. L-2-hydroxyglutarate and its enantiomer (the "mirror image" of the substance molecule), D-2 hydroxyglutarate, are formed as a result of specific changes in cellular metabolism in various types of cancer. As the pathological process progresses, the level of biomarkers in the body increases, and they accumulate in affected organs and tissues, as well as in the blood of cancer patients. Early detection of this biomarker and determination of its concentration in the body are crucial for developing a treatment strategy and assessing the effectiveness of cancer therapy. The sensor developers presented the results of their study in the article "Terahertz nanoantenna sensor for detecting the biomarker L-2-hydroxyglutarate: design optimization and testing" (“Terahertz nanoantenna sensor for detection of biomarker L‑2‑Hydroxyglutarate, design optimization and testing”), published in the journal Optical and Quantum Electronics.

— L-2-hydroxyglutarate plays an important role in many physiological processes and is considered as a biomarker for various types of cancer. An increase in its level occurs in malignant tumors of the brain, pancreas, kidneys and other organs. To correctly diagnose and predict the course of the disease, it is necessary to know what the concentration of L-2-hydroxyglutarate is in the patient’s organs and tissues. For these purposes, gas and liquid chromatography methods are currently used in combination with mass spectrometry to determine the level of this biomarker in blood serum and cerebrospinal fluid. These methods require complex sample preparation and expensive equipment. There are other diagnostic methods aimed at detecting changes in blood composition, but they require a long time and, as a rule, they are performed strictly according to medical indications. Some diseases develop covertly for a long time, so their timely detection is difficult. For example, glioma, a tumor that affects the glial cells of the brain or spinal cord, often does not make itself felt until a certain point, often appearing in late stages, when therapy is either ineffective or completely impossible. Therefore, we have attempted to develop optical systems capable of performing rapid diagnostics by detecting excess concentrations of L-2-hydroxyglutarate and D-2 hydroxyglutarate, as well as changes in their ratio. Our development can make it possible to detect oncological diseases in the early stages and, therefore, begin treatment in a timely manner,” said Nazar Nikolaev, Candidate of Technical Sciences, senior researcher at the Laboratory of Functional Diagnostics of Low-Dimensional Structures for Nanoelectronics, ATIC FF NSU, as well as the head of the Terahertz Photonics Laboratories at the Institute of Automation and Energy SB RAS.

A team of six scientists from NSU, the Institute of Automation and Electrometry SB RAS, and the A.V. Rzhanov Institute of Semiconductor Physics SB RAS collaborated on the development of new optical sensors. They drew on the research of their colleagues in China, who conducted spectroscopy of the biomarkers L-2-hydroxyglutarate and D-2 hydroxyglutarate and found that the spectra of these isomers in the far-infrared (terahertz) range differ. The L-isomer has a characteristic absorption peak near 1.337 THz, while the D-isomer has a peak near 1.695 THz. Based on these data, the laboratory's researchers developed a new type of optical sensor based on terahertz nanoantennas for detecting L-2-hydroxyglutarate in biological samples.

The device is an array of gold nanoantennas on a silicon substrate. NSU scientists performed electrodynamic calculations of the sensor structure and optimized the geometric parameters to excite plasmon resonance at the required frequency for this biomarker – 1.337 THz. The sensor was fabricated using nanolithography at the Institute of Semiconductor Physics SB RAS and characterized using scanning electron microscopy. Spectral measurements and testing of the sensor were conducted at the Spectroscopy and Optics Shared Use Center of the Institute of Automation SB RAS. Its specific sensitivity to the L-2-hydroxyglutarate biomarker was confirmed experimentally using pulsed terahertz spectroscopy. By monitoring the resonance behavior in the sensor's transmission spectrum with increasing L-2-hydroxyglutarate concentration, the researchers determined the sensor's sensitivity. The study identified the device's shortcomings and proposed a solution to improve its sensitivity and biomarker level detection accuracy.

The nanoantenna itself is a simple dipole resonator. With a length close to half the wavelength, it effectively interacts with the electromagnetic wave, whose energy is concentrated at the antenna ends. In our case, the antenna length is approximately 40 µm. The prefix "nano" means that we moved the antennas end-to-end and created the smallest possible gap between them. This gap is approximately 100 nanometers. The University team was tasked with optimizing the antenna dimensions to increase the field strength at a frequency of 1.337 THz in the nanogap. As the field strength increases, so does the sensor sensitivity. The sensor design itself was not new, but the engineering task of optimizing it for the terahertz frequency range was our first. After testing, we identified key ways to increase the sensitivity of this class of sensors, related to further increasing the signal-to-noise ratio and increasing the spectral resolution of the entire sensor system, for example, by applying an antireflective coating to the back of the sensor or increasing the thickness of its substrate, explained Nazar Nikolaev.

Scientists claim that in a similar way it is possible to make a sensor for detecting the biomarker D-2 hydroxyglutarate, which has a resonance frequency of about 1.695 THz, and, combining it with one already developed for the biomarker L-2-hydroxyglutarate, obtain a universal device that works to detect the amount of both isomers. However, in the process of working on these devices, they identified a number of shortcomings of the technical approach using nanoantennas. The plasmon surface resonance interacting with the biomarker molecule is an absorption resonance: interacting with an electromagnetic wave, the nanoantenna absorbs energy, and a dip is formed in the corresponding region of the spectrum. To assess the concentration of a biomarker, it is necessary to study changes in the characteristics of a given dip: amplitude, frequency shift. And a problem arises: due to the absorption of energy in this area, the signal-to-noise ratio decreases. Therefore, strong noise does not allow one to reliably determine the presence and concentration of a small amount of a substance. It became obvious that such a design as nanoantennas is not the optimal technical solution. Scientists have proposed another approach to solving the problem, based on an inverse structure, i.e. instead of thin metal strips (antennas) there are slits. The metal surface of the sensor must be solid, in which nano-sized slits are cut. This structure must have an inverse spectrum – not energy absorption at the operating frequency, but maximum transmission at a given frequency and suppression of other frequencies. Then the optimal signal amplitude and high signal-to-noise ratio will be achieved, which will improve the diagnostic accuracy. Now scientists have to translate the results of their research into a new device. They have already begun to develop a new sensor that will not have the shortcomings identified in the nanoantenna sensor. Work on it is expected to be completed this year.

We anticipate that the new sensor will produce more reliable results and lower measurement noise. If this is confirmed, we will be able to move on to testing not model solutions of the substance, as in the previous stage of research, but blood serum, which is a complex biological fluid. This will allow us to test our sensor for detecting the L-2-hydroxyglutarate biomarker under conditions close to real-world conditions. Potentially, if successful, our device could be used in clinical diagnostics. However, to test the sensor and detect this biomarker, we currently use expensive systems with a wide spectral range. Only specialized specialists with the skills to configure and process data can operate such laboratory equipment. However, since real-world practice requires only resonant frequency analysis, the entire diagnostic system can be simplified by transferring it to a more accessible single-frequency radiation source. With further development of the appropriate software, this diagnostic equipment could be used by medical professionals without the need for specialized physicists. However, even if our new sensor proves effective, it will require several years of engineering and design work, as well as the device's certification process, said Nazar Nikolaev.
