Abstract Organic optoelectronics have attracted widespread interdisciplinary research interest but lags far behind in the application marine environmental detection. The organic photoelectrochemical transistor (OPECT) shows promise as a powerful tool for comprehensive monitoring and early warning of conditions, which can be further enhanced by valuable signal amplification strategy nanozyme‐mediated catalytic precipitation. Herein, OPECT technology is integrated with precipitation first time, establishing an ultrasensitive detection platform okadaic acid (OA). Specifically, MXene@MnIn 2 S 4 (MXMnIS) hybrid composed Schottky‐junction synthesized via hydrothermal method, efficiently modulate device high current gain. Linking sandwich immunoassay, Ru‐C 3 N nanozyme peroxidase‐mimicking activity catalyze oxidation 4‐chloro‐1‐naphthol (4‐CN) to form insoluble precipitate on electrode surface, resulting decrease photocurrent altering response. Importantly, proposed biosensor presented excellent sensitivity low limit (32.5 pM), fully satisfying fundamental requirements quantitative intracellular extracellular OA practical culture media Prorocentrum lima at different growth stages. This based quenching effect significant effectively safety ecological environment food safety.

Abstract Flexible photoelectrochemical (PEC) based sensors have been extensively investigated for noninvasive healthcare monitoring. However, known electrode materials struggle to combine technologically relevant metrics of high sensitivity and flexibility due their low electrical conductivity fragile mechanical properties. Herein, a flexible PEC‐based sensor dopamine (DA) detection is presented by integrating highly conductive MXene between CdS quantum dots g‐C 3 N 4 with suitable energy level matching. Theoretical calculations reveal that the interfaces constructed PEC electrodes enhanced electronic derived from not only improve electron transfer kinetics, but form built‐in electric fields at interfaces, facilitating separation efficiency electron–hole pairs. As result, as‐prepared display combined advantages wide range (1 nM–0.1 mM), limit (0.48 nM), stability, selectivity, repeatability DA detection. Building on these metrics, scalable screen‐printing method further developed platforms. These all‐integrated exhibit stable photocurrent signals under different bending angles cycles. Therefore, this work demonstrates development sensitive holds promise future
