Self-Powered and Sensitive Assay of Caspase-3 Activity Based on an Ultralarge Photocathodic Current Amplified by Polydopamine Modification and a CdIn2S4/CdS Heterojunction Photoanode
{{output}}
Photocathodic analysis has an excellent anti-interference property but suffers from a weak response signal, restricting its sensitivity and applicability in trace-level assays. Here, a 55-fold amplification of the photocathodic response signal was achieved. On... ...
