Summary: To discriminate the signals of multi-targets in photoelectrochemical (PEC) detection, a non-instrument-assisted strategy for signal discrimination is proposed. This strategy utilizes exonuclease III-mediated multiple PEC signals resolution and a self-cleaning recyclable multiplexed PEC sensor. By cleaving the DNA strand attached to the magnetic bead, the signal labels can be separated, allowing for the generation of distinguishable photocurrent signals of different targets on a single photoelectric interface. The feasibility of this multiplexed sensor is verified by detecting two coexisting mycotoxins. The proposed sensing strategy eliminates instrumentation constraints and simplifies experimental procedures, providing a new idea for portable multiplexed PEC sensing devices.

Summary: An ultra-sensitive signal quenched photoelectrochemical (PEC) aptasensor was constructed for dibutyl phthalate (DBP) detection, using a target-induced cruciform DNA structure as signal amplifier and gC3N4/SnO2 composite as signal indicator. The designed cruciform DNA structure exhibited high signal amplification efficiency due to reduced steric hindrance, and the fabricated PEC biosensor showed a low detection limit of 0.3 fM for DBP in a wide linear range of 1 fM to 1 nM. This work provided a novel nucleic acid signal amplification approach for enhancing the sensitivity of PEC sensing platforms for the detection of phthalates (PAEs)-based plasticizer.

Summary: The Co3O4 nanoparticle-modified ITO electrodes were successfully prepared using dicarboxylic acid as a self-assembled monolayer. These electrodes showed high electrochemical catalytic activity for oxygen evolution reaction (OER) in acid. The most active assembly exhibited low overpotential and high OER current density, and the electron transfer rate constant was not affected by the carbon chain lengths but enhanced by the larger diameter of Co3O4 nanoparticles. Furthermore, shorter carbon chains and smaller Co3O4 nanoparticles increased the turnover frequency (TOF) of Co sites for OER.

Summary: A strand displacement amplification (SDA)-assisted CRISPR/Cas12a electrochemiluminescence (ECL) biosensor was developed for ultrasensitive detection of Staphylococcus aureus (Sa)-16S rDNA. The biosensor utilized a porphyrinic Zr metal-organic framework (MOF) as a coreactant accelerator to enhance the ECL emission signal. The presence of Sa-16S rDNA triggered the SDA reaction, generating single-stranded DNA products (SP) that activated the CRISPR/Cas12a trans-cleavage and effectively extinguished the ECL signals. The ECL platform exhibited high sensitivity and specificity, making it suitable for clinical diagnosis.
