Abstract

A photo-enhanced electrochemical (PEEC) and colorimetric (CM) dual-modal aptasensor was developed with rGO-AuNP Schottky contact for AFB1 monitoring. The PEEC mode allowed the ultrasensitive quantitation based on the photo-enhanced electroactivity mechanism, while the CM mode offered a rapid threshold-level qualitative assay with a portable colorimeter.
