Summary: In this study, carbon nitride quantum dots (CNQDs) with efficient near-infrared electrochemiluminescence (NIR-ECL) and excellent biocompatibility were prepared as an emitter to construct an ultrasensitive regenerative biosensing platform for detection of microRNA-222 (miRNA-222). The introduction of electron-rich pyrimidine effectively increased the conjugation effect of electrons on triazine ring in CNQDs, resulting in red shift of ECL emission wavelength. An improved circular DNA walker was assembled by the catalytic ligation of T4 DNA ligase to enhance its stability and walking efficiency. By utilizing CNQDs as emitter and circular DNA walker as signal amplifier, a regenerative biosensor platform was developed for ultrasensitive detection of miRNA-222 with high sensitivity and successfully applied for detection in cancer cells lysate. This work opens up a promising approach for synthesizing efficient NIR-ECL CNQDs, reducing damage to organisms and achieving deeper tissue penetration, and provides a new method for biomarker detection and disease diagnosis.

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.
