The in situ formation of a hole-transporting material on bismuth tungstate for innovative photoelectrochemical aptasensing

Chem Commun (Camb). 2021 Sep 6;57(71):8989-8992. doi: 10.1039/d1cc03745e.

Abstract

We present the in situ formation of a hole-transporting material (bismuth hexacyanoferrate) on the surface of bismuth tungstate aimed at an innovative photoelectrochemical strategy. This approach enabled a competent aptasensing platform for chloramphenicol that was amenable to homogenous, label-free, and split-mode detection.
