Summary: In this paper, a novel photoelectrochemical immunosensor based on a ZnO/CdSe semiconductor composite material was developed for the super-sensitive and quantitative detection of neuron-specific enolase (NSE). The antifouling interface composed of polyacrylic acid (PAA) and polyethylene glycol (PEG) effectively prevented non-specific protein adsorption. Ascorbic acid (AA) served as an electron donor, enhancing the stability and intensity of photocurrent by scavenging photogenerated holes. The PEC antifouling immunosensor exhibited a wide linear range (0.10 pg mL-1-100 ng mL-1) and a low detection limit (34 fg mL-1), making it a potential tool for clinical diagnosis of small cell lung cancer.

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: In this study, we demonstrate the diffusion-induced acceleration of charge transfer from Ru(bpy)32+-doped silica nanoparticles (RDSNs) to the electrode via electrochemiluminescence (ECL) imaging. The presence of Ru(bpy)32+ in the electrolyte enhances the ECL emission of RDSNs, and the emission intensity is amplified by 478 times when the free Ru(bpy)32+ concentration is 10 μM. The diffusion of Ru(bpy)33+ near a single RDSN enables faster charge transfer to the electrode than electron hopping in RDSN, as demonstrated by spatial and temporal interaction imaging of the RDSN and the Ru(III) diffusion layer.
