A carbon quantum layer modified BiVO₄ photoelectrochemical aptamer biosensor for ultra-sensitive cTnI biomarker detection based on the interface nephelauxetic effect and heterojunction assistance

Abstract

Photoinduced carriers’ separation, transport and aptamer probes immobilization are crucial factors to determine the sensitivity and specificity of semiconductor photoelectrochemical (PEC) aptamer biosensor. In this study, an in-situ thermal transformation...
