Professor Shenda: Smart Manufacturing New Crown "Scout" for 30 minutes to make the virus appear

At less than 9 o'clock in the morning, Zhang Yan, a special professor of the School of Physics and Optoelectronics Engineering, Shenzhen University, came to the Longhua Biological Industry Innovation Research Institute in Guanlan. Put on the experimental service and check the research progress in front of the computer. After a while, he summoned all team members to meet and arrange the next scientific research tasks. Unlike the quiet and peaceful campus, during the holidays, there is a busy school here. Just like the hot summer day outside the house, Zhang Yan and the members enjoy the hot holiday "golden time" with the hot air.

"Scientific research must be done, deepened, and thoroughly, and educated people must be attentive, pragmatic, and patient." In the interview, Zhang Yan said that the purpose of academic purpose is to serve life, and the purpose of education is to cultivate responsibility, responsibility, and adventure spirit. "Scientific Entrepreneurs" students.

Teach back to China, create "highlights of highlights" in scientific research

In the laboratory, Zhang Yan walked quickly and was almost a "running" attitude. However, when he stared at the experimental utensils or viewed the data, his eyes had never been removed for a long time, and the whole person seemed to be settled. In recent years, he has been selected as "Global High Scientists" for four consecutive years. He is currently the youngest American Optical Society winner. This year, he won the 24th "Guangdong Youth May 4th Medal". Behind the moment of "highlights", Zhang Yan's down -to -earth, climbing the peak, concentrating on the "unmanned area" in scientific research.

In 2006, after obtaining a bachelor's degree in physics and physics from Wuhan University, Zhang Yan went to Nanyang University of Science and Technology in Singapore and obtained a Ph.D. in Microelectronics Professional Institute of Technology in 2010. In the same year, he went to Brussels, Belgium, and was hired as a special professor and doctoral supervisor in Shenzhen University after completing post -doctoral studies in 2012. After returning to China, Zhang Yan established the first domestic black phosphorus laboratory to form a "sensory sensing" scientific research team. It is committed to black phosphorus research, basic semiconductor materials and chip development, sensor water quality monitoring technology and system development, new coronary virus testing Technology research and development and industrialization transformation. As of now, he has published more than 300 SCI papers, has applied for more than 300 patents, and has authorized more than 60 invention patents.

As one of the earliest batch of scholars in the world, after returning to China, Zhang Yan established the current black phosphorus engineering laboratory with the support of the Shenzhen Development and Reform Commission to carry out two -dimensional material research based on graphene. "Black phosphorus is a new semiconductor material, which is similar to graphene, but it can be comparable or even more than graphene in many features. At the same time, black phosphorus has good biocompatibility and has obvious advantages in targeted biological therapy. "Scientific research does not happen overnight. Even if the Zhang Yan team has broaden the border of black phosphorus application again and again, its broad application prospect has allowed him to move forward. "I believe in the future, there will be good news to bring everyone in the research and development of new materials such as black phosphorus." Zhang Yan said.

At present, the Zhangye team is guided by water quality safety and takes the lead in conducting comprehensive inspection for the environment in the country. In the latest scientific research, the scientific research team exceeded the technical difficulties in multi -field, created photonic CRISPR sensing methods, and successfully used it for rapid detection and typing of new coronal virus, with an accuracy rate of 99%.

Combination of industry, university and research, scientific research serving life

"Shenzhen's academic atmosphere and scientific research atmosphere have strong characteristics, and the scientific research has strong ability to transform. Many of our research can be landed immediately. In some places, we can pilot them. If the pilot results are good, it can be promoted in a large area."

For a long time, Shenzhen is committed to strengthening the innovative advantages of deep integration of industry, university and research, and accelerating the transformation of scientific and technological achievements to real productivity. This has a deep understanding of Zhang Yan and his team.

At present, the new sewage virus photoelectric sensing technology developed by Zhang Han and the team is a new type of nucleic acid sensing platform (MOPCS). During the holidays, the "All Things Sensing" team combined with the national latest sewage enrichment concentration and nucleic acid detection method standards, and conducted a new sewage new sewage new sewage monitoring in China When detecting residual new crown nucleic acid clips, early warning information is provided. "The traditional method of testing the new technical detection method has omitted the enlarged steps, which greatly shortens the detection time, and the specificity increases by more than 10 times. It can obtain new coronary virus infection information with an accuracy of 99.9%in 30 minutes, and accurately distinguish mutant poisons accurately. The type of plant greatly improves the accuracy and speed of the virus detection. "Zhang Yan said. The rapid detection of new sewage virus can achieve low cost and normalized new crown prevention and control, which not only significantly reduce the cost of resistance, but also exports Shenzhen experience for national anti -epidemic. However, in the early experiment, in order to eliminate the interference of the test results in the fake signal in the water body, the scientific research team conducted hundreds of thousands of comparison experiments with countless quality control experiments ... It is reported that this technology has now entered the pilot stage In the cooperation project with the Shenzhen Ecological and Environment Bureau, it is applied to the new crown testing of imported goods and the new sewage new crown testing, which has realized the rapid test of the new crown -positive cargo and the environmental security confirmation of the environmental security area. "Once MOPCS is proven to be feasible, we can pave the point in the important drainage outlets of various cities in the future. In order to save manpower and avoid cross -infection, the team is currently developing the rapid detection equipment of fully automatic sewage virus virus. Among them, it is used to fully automate the sampling to the detection process.

"The best scientific research is often derived from life, and the best academics often serve life." Zhang Yan believes that scientific research should solve the needs around him. Dr. Tang Yuxuan, a member of his team, agreed with this: "I originally reported the goal of posting an article and the fund of the fund. When simplifying its workflow, I suddenly understood why I was engaged in the industry. Because this industry needs technology and we need us. "

Teach according to their aptitude and cultivate scientists in the new era

While climbing the peak of science, Zhang Yan took the responsibility of cultivating newcomers in the times. In recent years, more than 10 students have been hired as young professors, including Harvard Assistant Professor and Outstanding Youth in Guangdong Province. When he returned to China in 2013, he made two goals for himself: continuous innovation in scientific research, and continuous breakthroughs in talent training. He must train entrepreneurs with scientists and scientists with the spirit of entrepreneurs. This is still pursuing Zhang Han to this day.

During the interview, Zhang Yan always used "completion" to describe the end of the experiment. When asked why he did not use "success", he said that innovation is spiral, and "completion" can better reflect the truth of scientific research. Talent training The same is true. "The difficulties in the research and development process are far greater than our imagination. Therefore, I hope that the team members will not be afraid of difficulties, be brave in troideation, and consider every detail of the technology. At the same time, I also hope that the members are persistent. Better, 10 experiments may have 9 times. Only by continuous persistence and continuous trial and error can we achieve our satisfactory results. "Zhang Yan believes that scientific researchers are not a simple, non -disciplined science and technology worker, but People who care about society and keep pace with the times. "Talk about the mistakes of the country, and the actual combat. We must combine the major national strategic policies to make the results of benefiting the country and the people and cultivating useful talents for the country."

As a young science and technology worker, he believes that young people should seize the golden age of learning skills, cultivate academic literacy, and accumulate original motivation. At the same time, he is diligent in asking senior professors and experts to stand on the shoulders of the past and see the world. In addition, young people should pay attention to current affairs hotspots and serve the country.

When the reporter ended the interview, Zhang Yan and two doctors were still playing with the new machine concentrate. As he said, he enjoys the process of seeing the progress of the experiment step by step, and the feeling is down -to -earth.
