Label-free “signal-off” PEC aptasensor for determination of kanamycin based on 3D nanoflower-like FeIn2S4/CdS Z-scheme heterostructures

A novel dual-model photoelectrochemical/electrochemical sensor based on Z-scheme TiO2 disks/methylene blue for kanamycin detection

“…Photoelectrochemical (PEC) sensors as a promising sensing technology, because of their advantages such as low cost, high sensitivity, low background signal, and miniaturization, have found applications in various fields, including food testing, environmental monitoring, genetic testing, and early clinical diagnosis. 13–18 The choice of suitable photoactive materials is crucial to construct PEC sensors as it affects their detection sensitivity. Titanium dioxide (TiO 2 ) has been widely used in PEC sensors because of its excellent photoelectrical activity and good biocompatibility.…”
