Abstract: A novel molecularly imprinted polymer (MIP) photoelectrochemical sensor was fabricated for the highly sensitive and selective detection of triclosan. The MIP photoelectrochemical sensor was fabricated using graphite-like carbon nitride (g-C3N4) and gold nanoparticles (AuNPs) as photoelectric materials. The MIP/g-C3N4-AuNPs sensor used photocurrent as the detection signal and was triggered by ultraviolet light (UV-Light 365 nm). g-C3N4-AuNPs was immobilized on indium tin oxide electrodes to produce the photoelectrochemically responsive electrode of the MIP/g-C3N4-AuNPs sensor. A MIP layer of poly-o-phenylenediamine was electropolymerized on the g-C3N4-AuNPs-modified electrode to act as the recognition element of the MIP/g-C3N4-AuNPs sensor and to enable the selective adsorption of triclosan to the sensor through specific binding. Under optimal experimental conditions, the designed MIP/g-C3N4-AuNPs sensor presented high sensitivity for triclosan with a linear range of 2 x 10-12 to 8 x 10-10 M and a limit of detection of 6.01 x 10-13 M. Moreover, the MIP/g-C3N4-AuNPs sensor showed excellent selectivity. The sensor had been successfully applied in the analysis of toothpaste samples
