Description

technical field

[0001] The invention relates to the technical field of analysis and detection, in particular to a wireless photoelectrochemical indirect analysis and detection device and a manufacturing method thereof. Background technique

[0002] In recent years, the analysis and testing technology based on photoelectrochemistry has made great progress, and its application range is more and more extensive. Photoelectric analysis has a series of advantages such as simple equipment, easy operation, and high sensitivity. At present, the basic strategy of photoelectric analysis is to modify the electrode surface of photoelectric active materials by irradiation of specific wavelengths of light. During this process, there will be mutual conversion between electrical energy, chemical energy and light energy, and electron transfer will occur between the detection object and the photoelectric semiconductor material. Thereby, a photocurrent is generated, and the detection of the ta...
