A Chemical Redox Cycling-Based Dual-Mode Biosensor for Self-Powered Photoelectrochemical and Colorimetric Assay of Heat Shock Protein

ACS Sensors, Год журнала: 2025, Номер unknown

Опубликована: Янв. 1, 2025

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.
