摘要

•A antibody-free MIP sensor was developed for photoelectrochemical AFP assay.•Heterostructured CdS@ZnO NAs could accelerate the separation of electron-hole pairs.•High sensitivity and low detection limit stemmed from PDA-MIP-decorated CdS@ZnO NAs.•This sensor achieved great prospect in the analysis of human serum samples.
