Research Progress in the Application of Photoelectrochemical Sensors in Food Safety Detection

Abstract:

Food safety is a major global issue concerning the national economy and people’s livelihood. Rapid, sensitive, and accurate detection of harmful substances in food is the key to ensuring food safety. As an emerging analytical technique, photoelectrochemical sensors combine photoelectric technology with biological sensing technology and have developed into a new type of photoelectric analysis sensors. They integrate the sensitivity of photochemistry and the simplicity of electrochemistry and have shown widespread applications in food safety detection due to their outstanding advantages such as high sensitivity, simple equipment, easy of miniaturization, and low costs. The author reviews the application examples and discusses the challenges of photoelectrochemical sensors in food safety detection, and makes an outlook on the future research directions.
