Interface self-shelling effect-mediated photoinduced carrier transport and multiplexed signal amplification mechanism in self-powered photoelectrochemical biosensing
In the realm of biomedical diagnostics, the development of sensitive and specific detection methods for cancer biomarkers is of paramount importance. Herein, we report on the design and implementation of a self-powered photoelectrochemical (PEC) sensor that harnesses amplified photocathode signals for the deterioration of carbohydrate antigen 125 (CA125) associated with ovarian cancer. This self-powered sensing platform integrates Cu
