Sandwich-type electrochemical aptasensor based on HMCS@PDA@AuNPs and PtCu DNs/MUN-CuO-TiO2 for ultrasensitive detection of cardiac troponin I

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

“…Currently, the main methods for cTnI detection include enzyme-linked immunosorbent assay (ELISA), solid-phase immunoassay, radioimmunoassay, chemiluminescence analysis, and others. 7–9 However, these methods have several limitations during application, for instance a cumbersome procedure, long detection time, and sensitivity limitation. 10 Therefore, it is of significant importance to develop highly sensitive, specific, and rapid methods for cTnI detection, to promote the early diagnosis of AMI.…”
