Target-Induced Chemical Reaction Modulated Optical Fiber-Gated Organic Photoelectrochemical Transistor for in Vivo H₂S Detection

Analytical Chemistry, Journal Year: 2025, Volume and Issue: unknown

Published: March 27, 2025

Real time detection of hydrogen sulfide (H2S) in deep brain regions is great significance. Photoelectrochemical (PEC) biosensors hold promise for real-time monitoring but low sensitivity due to the use small electrode restrained its application. In this study, a miniaturized sensor that integrates organic photoelectrochemical transistors (OPECTs) with optical fiber (OF) microelectrodes was designed first time, which can amplify PEC signal into large channel current change. A conductive gold layer and cuprous oxide nanoparticles (Cu2O NPs) were sequentially deposited onto OF, followed by Nafion polymer coating enhance anti-interference capabilities. Cu2O reacts H2S generate Cu2S. The resulting Cu2O/Cu2S heterojunction induces changes current. Compared conventional system, OPECT has higher lower limit, enabling concentration fluctuations within rat brain, demonstrates approach's capability highly sensitive vivo biomarker detection.

Construction of Frustrated Lewis Pairs for Efficient Artificial Enzyme

Advanced Functional Materials, Journal Year: 2025, Volume and Issue: unknown

Published: March 26, 2025

Abstract Optimizing the binding sites of substrates for small molecules activation plays a crucial role in enzyme‐like catalysts design. Herein, frustrated Lewis pairs (FLPs) are successfully constructed through boron (B) doping into CoO x (CoBO ) with abundant oxygen vacancies (O v ). The O optimizes valence active sites, creates coordinatively unsaturated state, and elongates distance pairs. electron‐deficient acid (LA) (Co) facilitate adsorption dissociation 2 , electron‐rich base (LB) (O) draw positively charged TMB closer to Co shorten reaction distance, which synergistically improve oxidase (OXD)‐like activity. Besides, increase electron density induced by FLPs promotes electrons transfer, intermediates stabilization, decreases energy barrier rate‐determining step . Significantly, proof‐of‐concept application colorimetric biosensing platform, as‐developed CoBO demonstrate highly sensitive selective detection capacity dopamine (DA) targets. This work verifies possibility activating catalysis.
