“…Although the excessive CIP in the solution can cause the photocurrent to continue to decrease through the spatial potential resistance effect, the decreasing trend is no longer linear. Compared with previously reported methods for CIP detection (Table S2), the proposed PEC ligand sensor displays excellent performance with a wide linear range and low LOD. − The improved performance of the proposed sensor is due to the rational space structure, good biocompatibility, excellent photoelectric conversion ability, and strong visible light absorption of the composite.…”

Accelerating the migration of interfacial carriers in heterojunctions is crucial for achieving highly sensitive photoelectrochemical (PEC) sensing. In this study, we developed three-dimensional (3D)/two-dimensional (2D) CuInS 2 /red phosphorus nanosheet (CuInS 2 /RP NS) n−n heterojunction functional materials with enhanced interfacial charge transfer capabilities for PEC sensing. The 3D CuInS 2 serves as a conductive layer, providing excellent electronic conductivity and superior electron absorption and transport properties. In contrast, the ultrathin RP NS acts as a transport layer that enhances carrier mobility. The 3D/2D heterojunction ensures a large interface contact surface, shortening the carrier transport distance. A well-aligned band position generates a substantial built-in electric field, providing a significant driving force for efficient carrier separation and migration, thereby improving response sensitivity. A PEC aptamer sensor was constructed based on the synthesized heterostructure for ciprofloxacin detection. The detection limit of the CuInS 2 /RP NS aptamer sensor for ciprofloxacin is 2.03 × 10 −15 mg•mL −1 , with a linear range from 1.0 × 10 −14 to 1.0 × 10 −5 mg•mL −1 . This work presents a strategy for enhancing the photoelectric response by modulating the interface structure of heterojunctions, thereby opening new prospects for the application of highly sensitive PEC sensors in antibiotic detection.

“…This dualphotoelectrode self-powered PEC sensing technology over- came the shortcomings of traditional sensing technologies, which require an external power supply and a three-electrode system, greatly simplifying the analytical equipment. Inspired by this achievement, Ouyang et al 63 fabricated a self-powered PEC sensing device by using 3D printing technology and injected the prepared nanomaterials into the device through a microchannel (Figure 4B-b). Under illumination, the device generated an OCP as the sensing signal to achieve sensitive detection of the target, further promoting the development of portable self-powered PEC sensors without an external power supply.…”

Revolutionary developments in analytical chemistry have led to the rapid development of self-powered photoelectrochemical (PEC) sensors. Different from conventional PEC sensors, self-powered PEC sensors do not require an external power source or complex devices for the sensitive detection of targets. As a result, these sensors have enormous application potential for the development of novel portable sensors. An increasing body of work is making excellent progress toward the implementation of self-powered PEC sensors for detection, but there have been no reviews to date. The present review first introduces the state of the art in the development of self-powered PEC sensors. Then, different types of self-powered PEC sensors are summarized and discussed in detail, including their current, power, and potential. Additionally, single-and dual-photoelectrode systems are classified and systematically compared. Finally, the current developments and major challenges that need to be addressed are also summarized. This review provides valuable insights into the current state of selfpowered PEC sensors to promote further progress in this field.
