Organic photoelectrochemical transistor (OPECT) has emerged as a promising technique for biomolecule detection, yet its operational rationale remains limited due to short development time. This study introduces stable tandem catalysis protocol by synergizing the enzyme-incorporated metal-organic frameworks (E-MOFs) with polyoxometalate (POM) nanozyme sensitive OPECT bioanalysis. The zeolitic imidazolate framework-8 (ZIF-8) acts skeleton protect encapsulated glucose oxidase (GOx), allowing catalytic generation of H

Organic photoelectrochemical transistor (OPECT) has undergone significant advancements, enabling an effective synergy between organic electronics and photoelectrochemistry, contributing to opto-logic gates, neuromorphic emulation, biological detection. However, feasible OPECT operation is still quite limited the associated technology evolving. This study introduces a self-enhancement facilitated by triple-functional stimuli-responsive molecules (SROM). The representative SROM sensitizes photogate selectively recognize chosen target, where reaction product serves reengineer band alignment, resulting in self-enhanced modulation. We further leverage this effect implement highly selective detection of sulfite. findings work bridge gap SROM, demonstrating potential unique implementation.

The judicious utilization of antibiotics has established a robust bulwark for human health. However, their improper usage engendered deleterious ramifications on the environment, underscoring imperative developing efficacious and cost-effective detection degradation platforms. This study presents sulfur-modified iron-cobalt bimetallic single-atom nitrogen-doped carbon catalyst (S-FeCo-NC) with noncopper active center. In contrast to conventional laccase, which utilizes copper as its center, S-FeCo-NC exhibits multiple enzyme activities, including laccase-like, peroxidase-like, catalase-like functions, iron cobalt serving centers. As proof concept, combined laccase-like functions were used independent signal outputs, while multienzyme cascade dual-mode assay system was designed rapid tetracycline (TC) in combination peroxidase-like enzymes. this system, oxygen directly participated catalytic process an electron acceptor, peroxidase efficiently catalyzed production O2 from H2O2. elevated concentration offered unique advantage increased activity enzyme, outputs visually resolved colorimetric signals using stable 4-aminopyridine oxidized TC. Furthermore, generation OH radicals strong oxidative properties, these carried out effective decomposition output response performed differential pulse cyclic voltammetry, further improved sensitivity accuracy detection. experimental findings demonstrate that favorable TC within range 0.005-500 μM, reaching 0.5-500 0.005-1.00 respectively, limit is low 0.22 μM 1.68 nM, respectively. based activity, been shown significantly enhance also demonstrating stability lower range. suggests it may offer novel approach sensitive environmental pollutants.
