Selective Sensing of Catechol Based on a Fluorescent Nanozyme With Catechol Oxidase Activity

Spectrochimica Acta - Part A: Molecular and Biomolecular Spectroscopy, 2023
Nanozymes, an unusual category of nanomaterials possessing enzymatic properties, and have generated considerable interest regarding their application feasibilities on several important fronts. In the present work, an innovative sensing device for catechol was established ground on a fluorescent nanozyme (Cu-BDC-NH2) that exhibited catechol oxidase ...

The Catalytic Cycle of Catechol Oxidase

Journal of Biological Inorganic Chemistry, 2004
Hybrid density functional theory with the B3LYP functional has been used to investigate the catalytic mechanism of catechol oxidase. Catechol oxidase belongs to a class of enzymes that has a copper dimer with histidine ligands at the active site. Another member of this class is tyrosinase, which has been studied by similar methods previously.

Oxidation of Catechol by Tea-Oxidase

Nature, 1950
DURING the enzymic oxidation of catechol, approximately two atoms of oxygen are taken up for each molecule of catechol, whereas only one atom is required for oxidation to the o-quinone stage. Wagreich and Nelson1 consider this extra uptake to be accounted for by the interaction of the o-benz-quinone with water to form 1 : 2 : 4-trihydroxy-benzene ...

Amperometric Catechol Biosensor Based on Polyaniline–Polyphenol Oxidase

Biosensors and Bioelectronics, 2010
A novel catechol biosensor was described based on the immobilization of polyphenol oxidase (PPO) into polyaniline (PANI), which was easily constructed by direct electropolymerization of aniline in a solution containing ionic liquid, 1-ethyl-3-methylimidazolium ethyl sulfate (EMIES).
