Abstract:

Photoelectrochemical (PEC) bioanalysis is a newly established analytical approach based on the photo- to-electrical properties of photoactive materials. It possesses many intrinsic advantages such as remarkable sensitivity, simple instrument, and inherent miniaturization. From the combination of photoelectrochemistry and bioanalysis, PEC bioanalysis has advantageously inherited the high sensitivity and specificity. Its general sensing mechanism is that, upon illumination, the photoactive materials could convert the specific biorecognition events into electrical signals, thereby realizing the quantification of various analytes. In past years, the rapid development of PEC bioanalysis has attracted considerable interest, and significant progress has been achieved in its advancement and application. This talk introduces the basic principles, classification, characteristics, as well as the recent progress of PEC bioanalysis in our group.
