Summary: An efficient photoelectrochemical (PEC) split-type sensor based on a controlled release strategy was successfully established for ultrasensitive and accurate physiological monitoring, with improved visible light absorption efficiency and stability. The sensor separated the immune reaction from the photoelectrochemical conversion process, eliminating interference. The use of Cu2O nanocubes as labels and acid etching improved the sensitivity of the sensor. Under optimized conditions, the PEC sensor showed a wide concentration linear range and a low detection limit for CYFRA21-1 target detection.

Summary: In this study, a mesoporous silica nanospheres (MSNs)-assisted split-type photoelectrochemical (PEC) aptasensor with in situ generation of Bi2S3 was proposed for reliable detection of prostate-specific antigen (PSA). The release of Na2S, induced by the reaction between PSA and aptamer, led to the formation of BiOI/BiOBr/Bi2S3 composite, altering the electron-hole transfer pathway and decreasing the photocurrent response. The sensor exhibited a linear range of 10 pg·mL-1-1 μg·mL-1 and a detection limit of 1.23 pg·mL-1, demonstrating satisfactory stability and anti-interference.

Summary: A split-type photoelectrochemical immunosensor was designed to detect neuron-specific enolase (NSE), a tumor marker for small cell lung cancer found in nerve and neuroendocrine tissues. In this study, a heterogeneous In2O3/BiVO4 structure was developed using simplified successive ionic layer adsorption and reaction (s-SILAR). Immune recognition occurred in a 96-well plate, avoiding interference with biomolecule recognition. By regulating the degradation of the ZIF-8 protective layer, the split-type PEC immunosensor achieved sensitive detection of NSE.

Summary: A non-enzymatic photoelectrochemical method using a CdS|TiO2 nanotubes photoanode is proposed for the detection of aqueous sulfide and ascorbic acid. The sensitivity of both the CdS|TiO2 and CdS|Pt photoanodes is high in the visible range, allowing for detection at micromolar levels for sulfide and ascorbic acid. However, the detection of H2O2 leads to the degradation of CdS and the release of Cd2+ ions into the analyte solution.

Summary: A split-type photoelectrochemical (PEC) sensor based on Ti3C2/MgIn2S4 has been proposed for sensitive and accurate detection of miRNA-21. The Ti3C2/MgIn2S4 heterojunction effectively separates photogenerated electrons and holes, while a multifunctional PCN-224 nanocontainer amplifies the signal. The sensor achieved enhanced photocurrent response by releasing trapped glucose and utilizing glucose oxidase to generate hydrogen peroxide.

Summary: A split-type photoelectrochemical (PEC) sensor was designed using magnetic-assisted exciton-plasmon interactions (EPI) to detect profenofos (PFF). Core-shell Bi2S3 nanorods@MoS2 nanosheets (Bi2S3 NRs@MoS2 NSs) heterostructure nanomaterial with excellent performance was synthesized and utilized as the photovoltaic conversion substrate and signal molecules absorption platform. The proposed PEC sensor demonstrated outstanding analytical performances, including a wide linear range, low detection limitation, excellent specificity, high stability, and applicability. Furthermore, it provided a new signal strategy for PEC biosensors and extended their application in environmental analysis.

Summary: The photoelectrochemical (PEC) performance of nano-semiconductor materials can be enhanced by preventing carrier recombination. Here, CdS/ xNiO nano-semiconductor materials were synthesized using atomic layer deposition (ALD) technique. The deposition of NiO effectively inhibited the carrier recombination rate of CdS. A glucose biosensor based on CdS/80NiO showed excellent PEC performance and was successfully developed for simple, fast, sensitive, and label-free glucose detection.

Summary: In this study, g-C3N4@CdS composites were used as sensing elements in a photoelectrochemical platform for the rapid, selective, and sensitive detection of L-cysteine. The system exhibited a wide determination range (5-190 μM), a very low detection limit (1.56 μM), fast response time, and good long-term stability (approximately 1 month). The g-C3N4@CdS composites provided better optoelectronic function than bare CdS materials due to their high photon-to-current conversion efficiency and excellent anti-photocorrosion properties. Additionally, without any separation procedures, low concentrations of L-cysteine were successfully detected in human urine samples, consistent with the results of chemiluminescence.

Summary: In this study, a sandwich sensing platform was developed using silica-coated silver nanoparticles as a luminescent material and cerium dioxide as a signal quencher for sensitive neuro-specific enolase detection. The core-shell structure protected the silver nanoparticles and improved their luminescence properties. Amino-functionalized cerium dioxide efficiently diminished the luminescence signal, resulting in a highly sensitive and accurate detection mode. This detection strategy showed a powerful capability for biomolecule detection.
