WebMay 10, 2024 · The NSs inherit high porosity, a large specific surface, and a large number of active sites. They display superior oxidase-mimicking activity and can catalyze the oxidation of tetramethylbenzidine (TMB) by molecular oxygen to form blue oxTMB. Glutathione (GSH) can reduce oxTMB, so that less blue oxTMB will be present. WebThe detection limits of AChE and paraoxon reached 35 μU mL −1 and 1.0 ng mL −1, respectively. Furthermore, the MnO 2 -TMB platform has been used to fabricate test strips for rapid and convenient visual detection of AChE …

WebIn particular, Fe,N-GQDs exhibit very high peroxidase-mimicking activity and can rapidly oxidize peroxidase substrates 3,3′,5,5′-tetramethylbenzidine (TMB) to produce blue oxidized TMB (oxTMB) in the presence of H 2 O 2. WebJan 8, 2024 · In the presence of Hx, XOD can quantitatively convert Hx to H 2 O 2, and the generated H 2 O 2 can further oxidize the colorless 3,3′,5,5′-Tetramethylbenzidine (TMB) to blue oxTMB with the catalysis of Fe-PDA. However, these biosensors still need the assistance of the natural enzyme (XOD), which meant it was difficult to avoid the …
WebTMB can be efficiently oxidized to generate oxidized TMB (oxTMB) by HAuCl4, which displays four characteristic absorption peaks. The presence of different bacteria could inhibit the oxidation reaction and cause diverse changes in the intensity of the four characteristic peaks. Based on linear discriminant analysis (LDA), not only are nine kinds ... WebNov 28, 2024 · The possible reaction mechanism involves two steps where the O O bond in H 2 O 2 molecule was broken into ·OH followed by TMB oxidation by ·OH to form oxTMB. …
WebMar 1, 2024 · After being further introduced TMB into the detection system, TMB would be oxidized by MnO 2 /IR780 NSs to form oxTMB. As a result, the temperature noticeably elevated upon NIR laser irradiation. Consequently, highly sensitive detection of tumor exosomes was readily achieved. WebThe reduction of oxidated TMB (oxTMB) reports the presence of AA. Specifically, oxTMB was first generated by adding H 2 O 2 (6.6 mM) in the medium for 30 min reaction at …
