“…The proposed PEC aptasensor was able to detect acetamiprid concentrations in the range of 0.5 pM to 10 µM with an LOD of 0.2 pM and was successfully applied to the direct detection of spiked apple and tomato samples. A split-type PEC sensor was designed for the detection of profenofos based on magneticassisted exciton-plasmon interactions (EPIs) [157] (Figure 6d). The target-triggered DNA double-stranded structure opening event released Au NPs-cDNA, which had significant overlap in the spectra of the Bi 2 S 3 /MoS 2 substrate.…”

Pesticides have become an integral part of modern agricultural practices, but their widespread use poses a significant threat to human health. As such, there is a pressing need to develop effective methods for detecting pesticides in food and environmental samples. Traditional chromatography methods and common rapid detection methods cannot satisfy accuracy, portability, long storage time, and solution stability at the same time. In recent years, photoelectrochemical (PEC) sensing technology has gained attention as a promising approach for detecting various pesticides due to its salient advantages, including high sensitivity, low cost, simple operation, fast response, and easy miniaturization, thus becoming a competitive candidate for real-time and on-site monitoring of pesticide levels. This review provides an overview of the recent advancements in PEC methods for pesticide detection and their applications in ensuring food and environmental safety, with a focus on the categories of photoactive materials, from single semiconductor to semiconductor–semiconductor heterojunction, and signaling mechanisms of PEC sensing platforms, including oxidation of pesticides, steric hindrance, generation/decrease in sacrificial agents, and introduction/release of photoactive materials. Additionally, this review will offer insights into future prospects and confrontations, thereby contributing novel perspectives to this evolving domain.
