The traditional biocatalytic precipitation (BCP) strategy often required the participation of H2O2, but H2O2 had problem self-decomposition, which prevented its application in quantitative analysis. This work first found that a bimetallic single-atom catalyst (Co/Zn–N–C SAC) could effectively activate dissolved O2 to produce reactive oxygen species (ROS) due superior oxidase (OXD)-like activity. Experimental investigations demonstrated Co/Zn–N–C SAC preferred highly active hydroxyl radicals (•OH), oxidized 3-amino-9-ethyl carbazole (AEC) reddish-brown insoluble precipitates. Based on this property, unique oxygen-activated photoelectrochemical (PEC) biosensor was developed for chloramphenicol (CAP) detection. Cesium platinum bromide nanocrystals (Cs2PtBr6 NCs) were new type halide perovskite with lead-free, narrow band gaps, and water-oxygen resistance. Cs2PtBr6 NCs showed excellent cathodal PEC performance without an exogenous coreactant used As "proof-of-concept application", introduced onto surface by using CAP dual-aptamer sandwich strategy. activated ROS, AEC precipitates, quenching signal In summary, overcome restriction enzymatic BCP requiring improved stability accuracy analysis, also broadened range coreactant-free perovskite-type biosensors.

In this work, the relationship between electrochemiluminescence (ECL) signal and driving voltage was first studied by self-made reduced oxidized closed bipolar electrodes (CBPEs). It found that when large enough, maximum ECL signals for two kinds of CBPEs were same but their required drive voltages different. Zinc cobalt nitrogen doped carbon material (ZnCoN-C) had an outstanding electric double layer (EDL) property conductivity. Therefore, it could significantly reduce CBPE systems, reaching Ru(bpy)32+. Interestingly, ZnCoN-C modified electrode reached signal, bare zero. As a proof-of-concept application, zero-background dual-mode CBPE-ECL biosensor constructed ultrasensitive detection ochratoxin A (OTA) in beer. Considering beer samples contained number reducing substances, system selected to build biosensor. Furthermore, convenient imaging platform using smartphone built OTA. This work used unique EDL regulate time; thus, novel sensor constructed. Further, provided deeper understanding opened new door detection.
