To advance the biological understanding of heat shock protein (HSP) in different types cancers, it is crucial to achieve its accurate determination. Herein, a dual-mode self-powered photoelectrochemical (PEC) and colorimetric platform was proposed by integrating enzymatic catalysis chemical redox cycling amplification strategy. In this system, ascorbic acid (AA), as signal reporter for PEC assay, can be regenerated during tris(2-carboxyethyl) phosphine-mediated process. For detection, reproduced electron donor AA could repeatedly combine with holes generated Bi

Organic photoelectrochemical transistor (OPECT) has shown substantial potential in the development of next-generation bioanalysis yet is limited by either-or situation between photoelectrode types and channel types. Inspired dual-photoelectrode systems, we propose a new architecture dual-engine OPECT for enhanced signal modulation its biosensing application. Exemplified incorporating CdS/Bi2S3 photoanode Cu2O photocathode within gate-source circuit Ag/AgCl-gated poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) channel, device shows capability larger transconductance (gm) against single-photoelectrode ones. Moreover, light irritation upon effectively shifts peak value gm to zero gate voltage without degradation generates current steps that are advantageous sensitive bioanalysis. Based on as-developed OPECT, target-mediated recycling etching reactions designed CdS/Bi2S3, which could result dual amplification realize microRNA-155 biodetection with linear range from 1 fM 100 pM lower detection limit 0.12 fM.

A novel dual-mode microfluidic sensing platform integrating photoelectrochemical (PEC) and fluorescence (FL) sensors was developed for the sensitive monitoring of heart fatty acid binding protein (h-FABP). First, BiVO4/AgInS2 (BVAIS) composites with excellent photoelectric activity were synthesized as matrices. The BVAIS heterojunction a well-matched internal energy level structure provided stable photocurrent. Second, an innovative signal amplification strategy based on octylamine-modified poly(acrylic acid) (OPA)-capped CsPbBr3 (OPCB) nanocrystals (NCs) catalytic property proposed. On OPCB nanozyme possessing ascorbate oxidase-like could catalyze oxidation ascorbic acid, which achieved quenching photocurrent signals by competitively consuming electron donor. other hand, NCs that overcame water stability defect processed good luminescence performance able to produce obvious FL signals. Mutually verified dual-response effectively enhance precision test outcomes avoid false-positive or false-negative results. Finally, constructed realized detection h-FABP in linear range 0.0001–150 ng/mL (PEC mode) 0.001–150 (FL mode), limits 36 fg/mL 0.32 pg/mL, respectively. present work new perspective designing efficient achieve disease markers.
