Three achievements of key projects of “Science and Technology Strengthening Police” passed the identification of new products in Anhui Province

[ Instrument Network Instrument Development ] On September 30th, the three key achievements of the “Science and Technology Strong Police” key project hosted or participated by the Hefei Institute of Material Science of the Chinese Academy of Sciences were “Portable Drug Rapid Detection System”, “Hair Drug Rapid Detection System” and “Multichannel”. The portable drug on-site inspection box was identified in Hefei by Anhui Province.

Dr. Li Pan and Dr. Dong Ronglu from the Research Team of Yang Liangbao of the Center for Medical Physics and Technology, on behalf of the R&D team, reported to the Identification Expert Group the “Portable Drug Rapid Detection System”, “Hair Drug Rapid Detection System” and “Multi-channel Portable Drug Field Detection Box”. Product development and demonstration applications. Among them, the portable drug rapid detector uses high-sensitivity surface-enhanced Raman spectroscopy to solve the problem of trace drug detection of weak signals; the rapid detection system of hair drugs uses automatic detection, intelligent recognition and other technologies to solve the rapid hair sample. Screening problems improve the efficiency of rapid drug screening in hair; multi-channel portable drug field testing kits combine specially designed sample slots and pre-treatment techniques to enable rapid on-site detection of drugs in saliva and urine. Around the three new products, related technologies have been submitted for 4 invention patent applications and 5 utility model patents.

The new product appraisal committee is composed of experts from the University of Science and Technology of China, Anhui University, Anhui Electronic Product Supervision and Inspection Institute, Anhui Provincial Public Security Department, etc. Professor Wang Nian of Anhui University serves as the chairman of the appraisal committee. The experts from the conference, Professor Wang Nian, Wu Yongdong, senior engineer, Professor Chang Changan, Professor Xiong Yan, Sun Yining, and Hu Xian, the researchers, listened carefully to the project team's report on the development of the three products, and reviewed the product development and testing sites. The relevant technical materials were reviewed, and the team's work in the transformation of technological achievements and new product development was fully affirmed. It was agreed that the three results passed the appraisal of new product results.

At present, the prevalence of drugs worldwide and the abuse of psychoactive substances have led to an increase in the number of drug users and a threat to public health. Surface-enhanced Raman spectroscopy is the best choice for rapid drug detection due to its high sensitivity, fingerprint recognition and fastness. All three products are based on surface enhanced Raman spectroscopy (SERS) technology to achieve rapid detection of drugs, and to achieve rapid detection and identification of suspected drug transactions, suspected drug abuse sites, suspected drug users and new synthetic drugs, thereby strengthening public security, national defense And the efficiency of the customs department in drug investigation.
