Processor of Nankai University Develops World-leading Pesticide-Residue Sensing Technology
Jointly developed by Nankai University, Tianjin Boao Electric Engineering Consulting Co., Ltd., and Tianjin Pesticide Research Institute, the “key technology for developing pesticide-residue sensors” was appraised by experts organized by the Tianjin High-Tech Transfer Center as a technology of “world-leading” level.
Undertaken by the Prof. Chen Qiang-Led Team at the School of Life Science, Nankai University, the project belongs to a scientific and technological project titled “The Development and Industrialization of Pesticide-Residue Sensors” (Contract No. 06YFGPNC03900). Through years’ joint research and development, the team managed to take the lead in utilizing the same technical system to efficiently and stably fix two enzymes on the surface of the electrode, breaking through the technical barrier that in the past, only a single enzyme could be fixed. The team therefore developed an acetylcholine sensor used for detecting pesticide residues, putting nanometer-scaled enzyme sensors featuring single or composite enzyme membranes into practical use. The developed pesticide-residue biosensor can perform high-speed detection of pesticide residues, and as proved by test, has the advantages of high stability, accurate detection results, high speed, strong anti-interference capability, etc. The sensor can be widely applied to such fields as industrial control, analysis of food and farm products, environmental projection, etc., and has strong practicality and good prospects for application. Appraisal by experts: the key technology is highly innovative and has reached the world-leading level.
By far, the team has been granted a patent of invention and a patent of utility model for the project, and has filed an application for another patent of invention, which has been received and publicized for soliciting public opinions.
