FeMoO₄nanospheres-based nanozymatic colorimetry for rapid and sensitive pyrophosphate detection

Abstract

Assays of pyrophosphate ion (PPi) are of remarkable biochemical significance due to its vital roles in the bioenergetic and metabolic processes or as the disease indicators. Colorimetry is popular in...

Effective antibacterial action of a 2D bimetallic Al/Fe-TCPP NMOF loaded with glucose oxidase by a cascade catalytic reaction and depleting glutathione simultaneously

“…To identify the type of ROS, terephthalic acid (TA) was used as an indicator because TA can be oxidized to 2-hydroxy terephthalic acid (TAOH) with blue fluorescence in the presence of ˙OH. 38 As shown in Fig. S8 (ESI†), the fluorescence spectra demonstrated that an obvious fluorescence emission peak at about 430 nm emerged in a mixture consisting of glucose, Al/Fe-TCPP NMOF/GO x and TA.…”

“…S8 (ESI †), the fluorescence spectra demonstrated that an obvious fluorescence emission peak at about 430 nm emerged in a mixture consisting of glucose, Al/Fe-TCPP NMOF/GOx and TA. 38 In contrast, no fluorescence emission was observed in the mixture of TA with glucose or Al/Fe-TCPP NMOF/ GOx. The results confirmed that the ROS generated in the mixture of glucose, TA and Al/Fe-TCPP NMOF/GOx were OH.…”

Microwave-assisted synthesis of green fluorescent copper nanoclusters: a novel approach for sensing of hydroxyl radicals and pyrophosphate ions via a “turn-off–on” mechanism

“…The correlation coefficient (R 2 ) is fairly good (R 2 = 0.993), favorable to attain an impressive LOD of 0.68 nM for PPi. The analytical efficiency of the coffee-Tryp-CuNCs-based fluorescence sensor is compared to the reported approaches [38][39][40][41][42][43][44][45][46][47][48][49][50][51] for detecting of OH and PPi, as shown in Tables 1 and 2.…”

A MOF-Templated Double-Shelled Co3O4/NiCo2O4 Nanocomposite for Electrochemical Detection of Alfuzosin

“…Electrochemical methods provide a compelling alternative for AFZ detection, due to their simplicity, speed, cost-effectiveness, and sensitivity [13][14][15][16][17][18][19]. Electrochemical sensors operate based on the redox reactions of the analyte at the electrode surface, generating a measurable current or potential signal [20][21][22][23].…”
