A highly sensitive TiO2-based molecularly imprinted photoelectrochemical sensor with regulation of imprinted sites by Photo-deposition

Here we constructed a highly sensitive molecularly imprinted photoelectrochemical sensor (MIPES) TiO2 NRs/NiOOH/rMIP for ciprofloxacin (CIP), in which photoactive sites of TiO2 were identified by NiOOH photo-deposition and the imprinted sites were anchored on the photoactive sites by complexation between CIP and NiOOH. The regulation of imprinted sites increased the photocurrent difference before and after the addition of CIP, thus improving the detection sensitivity of CIP.
