Abstract Organic electrochemical transistors showing maximum transconductance ( g m ) at zero gate bias V G is desired but has long been a challenge. To date, few solutions to this issue are available. Light‐matter interplay shown as rich sources for optogenetics, photodynamic therapy, and advanced electronics, its potential in modulation largely untapped. Herein, the challenge addressed by unique light‐matter newly emerged technique of organic photoelectrochemical transistor (OPECT), which...

DNAzyme-based cascade networks are effective tools to achieve ultrasensitive detection of low-abundance miRNAs. However, their designs complicated and costly, the operation is time-consuming. Herein, a novel simple noncascade DNAzyme network designed its amplification effect comparable or even better than many cascading ones. It nonenzymatic, isothermal, bicirculating consisting two toehold-mediated strand-displacement reactions localized strategy. Taking microRNA-122 as target model, this...

Semiconductor metal–organic frameworks (MOFs) and heterojunctions have gained increasing attention in many fields, yet their full potential remains largely unexplored. Advanced optobioelectronics are envisioned to create more opportunities for innovative biomedical applications. This study reports a UiO-66-NH2 (U6N)/CdS quantum dots (QDs)-gated organic photoelectrochemical transistor (OPECT) its application toward energy-transfer-based sensitive microRNA-166a (miRNA-166a) detection assisted...

Abstract (110)‐oriented zeolitic imidazolate framework (ZIF)‐8 thin films with controllable thickness are successfully deposited on indium tin oxide (ITO) electrodes at room temperature. The method applied uses 3‐aminopropyltriethoxysilane (APTES) in the form of self‐assembled monolayers (SAMs), followed by a subsequent adoption layer‐by‐layer (LBL) method. crystallographic preferential orientation (CPO) index shows that ZIF‐8 (110)‐oriented. A possible mechanism for growth modified ITO is...

Photoelectrochemical sensing has developed rapidly in the past decade because of its inherent advantages economic devices and low background noise. However, traditional assembly photoelectric beacons, probes, targets on ITO electrode solid–liquid interface inevitably leads to time-consuming, limited selectivity, poor stability, nonreproducibility. To overcome these drawbacks, this work, a unique split-type PEC aptasensor for carcinoembryonic antigen (CEA) was virtue sandwich-like structure...

An indirect photoelectrochemical sensing platform for toxic hexavalent chromium was the first time constructed based on its redox reaction with quercetin as both electron donor and photosensitizer a TiO(2) photoanode, thus inhibiting photocurrent quantitatively selectively. The presence of even 500-fold coexisting Cr(III) does not interfere in detection Cr(VI). Under optimum conditions, electrode displayed linear decrease response Cr(VI) concentration increased from 1 to 10 nmol L(-1) 20 140...
