MIL-68(In)-derived CdIn2S4 @In2S3 hollow microtubes for sensitive molecularly imprinted photoelectrochemical CEA sensor

Herein, an antibody-free photoelectrochemical sensing platform was constructed for sensitive carcinoembryonic antigen (CEA) assay by coupling with CdIn 2 S 4 @In 2 S 3 hollow microtubes (HMTs) and polydopamine-mediated molecularly imprinted polymer (MIP). Among them, CdIn 2 S 4 @In 2 S 3 ...
