Interfacial Charge Separation Engineering-Modulated Multichannel Photoelectrochemical Biosensor Enabled by a Triple-Responsive Nanolabel.
Accurate biomarker detection is crucial for early and accurate disease diagnosis. Herein, a multiplexed biosensor capable of simultaneous electrochemical (EC) and photoelectrochemical (PEC) operation is fabricated using efficient, self-templated In2S3/CuInS2 (CIS) heterostructured nanotubes for the selective detection...
