Current-decoupling electrochemical-photoelectrochemical biosensors for the simultaneous detection of coexisting cancer biomarkers miR-155 and miR-451.
Electrochemical (EC) and photoelectrochemical (PEC) biosensors offer accuracy, convenience, and affordability, making them ideal for early cancer screening. However, in conventional EC and PEC biosensors, signal crosstalk between the photocurrent and redox currents poses a significant challenge for the simultaneous det...
