On March 21, 2025, Feng Liang, a researcher from Dalian Institute of Chemical Physics, Chinese Academy of Sciences, was invited to visit the Institute of New Concept Sensors and Molecular Materials, and gave a report titled “Research and Application of Film-based Chemical Sensors”.

Feng Liang’s team has been committed to the surface and interface regulation of sensor sensitive films and the efficient capture of analytes molecules, and has conducted in-depth research in the rapid detection of paper-based sensors and some of them have achieved industrial applications. The report focuses on the rapid, trace and portable detection strategies of photochemical colorimetry and fluorescence sensor arrays for various toxic and harmful substances and pesticide residues, the construction of the characteristic “fingerprint” of analytes based on the interactive response signals of analytes, and the use of mathematical statistics analysis and big data intelligent operation to improve the comprehensive performance of optical sensors. In addition, the report also describes the team’s research progress in the field of new miniaturized, portable optical sensors.

The report was moderated by Prof. Ding Liping, and attended by more than 50 people, including teachers and students of the Institute, who discussed with Feng Liang in issues of the research and application of film-based chemical sensors.
