One-pot synthesized copper-imidazole-2-carboxaldehyde complex material with oxidase-like activity for the colorimetric detection of glutathione and ascorbic acid

Nanolevel of detection of ascorbic acid using horse-radish peroxidase inhibition assay

“…Additionally, there has been work on carbon nanodots and paper-based assay, where the former lowered detection limit while maintaining an increase in sensitivity as well as selectivity while the latter decreased the cost of production [ 18 , 19 ]. AA was detected using TMB with other types of oxidizing agents with oxidase-like and/or peroxidase-like activity such as such as Ce-BPyDC, Co–Fe Prussian blue analogue nanocube (Co–Fe PBA NC), Cu-imidazole-2-carboxaldehyde (Cu-ICA) and Fe–Mn bimetallic nanozyme (FeMnzyme) [ 17 , [20] , [21] , [22] ].…”
