A Computational and Spectroscopic Approach to Elucidate the Coordination Structures in Iron–Catechol Polymers

open access: yesChemistry Proceedings
Coordination polymer particles (CPPs) with catechol functionalities present significant potential for various applications. To elucidate their structural features, we synthesized CPPs using bidentate bis-catechol and catechol–pyridine ligands and ...

The catalytic role of uranyl in formation of polycatechol complexes

open access: yesChemistry Central Journal, 2011
To better understand the association of contaminant uranium with natural organic matter (NOM) and the fate of uranium in ground water, spectroscopic studies of uranium complexation with catechol were conducted.

A Novel Catechol Oxidase Enzyme Electrode for the Specific Determination of Catechol

open access: yesBioscience, Biotechnology, and Biochemistry, 1998
An enzyme electrode for the specific determination of catechol was developed by using catechol oxidase (EC 1.10.3.1) from eggplant (Solanum melangena L.) in combination with a dissolved oxygen probe. Optimization studies of the prepared catechol oxidase enzyme electrode established a phosphate buffer 50 mM at pH 7.0 and 35°C to provide the optimum ...

Electro-catalytic oxidation of catechol at poly(1-amino-9,10–anthraquinone)-SDS composite film

open access: yesActa Chimica Slovenica, 2016
An electro-chemically active composite film containing the environmentally friendly surfactant sodium dodecyl sulfate (SDS) and poly(1-amino-9,10-anthraquinone) (PAAQ) is used as an electron transfer mediator in the electro-chemical oxidation of catechol.

Plant-inspired adhesive and tough hydrogel based on Ag-Lignin nanoparticles-triggered dynamic redox catechol chemistry

open access: yesNature Communications, 2019
Biomimetic catechol-based adhesives have attracted significant interest but can lose adhesion due to excessive oxidation. Here, the authors report on the addition of silver-Lignin nanoparticles as a dynamic catechol redox system to maintain catechol ...

THE BACTERIAL DEGRADATION OF CATECHOL [PDF]

open access: yesBiochemical Journal, 1965
1. Two strains of Pseudomonas were grown with phenol and used to prepare cell extracts that metabolized catechol with the transient formation of 2-hydroxymuconic semialdehyde. 2. One of these preparations catalysed the conversion of 1mol. of catechol into 1mol. each of formate and 4-hydroxy-2-oxovalerate. 3.

Strain‐Programmable Luminescent Adhesive Patch With Tartrazine‐Mediated Optical Skin Clearing for Photochemical Tissue Bonding

open access: yesAdvanced Functional Materials, EarlyView.
We propose a suture‐complementary approach that integrates optical skin clearing with a strain‐programmable luminescent adhesive patch. Hyaluronic acid promotes transdermal delivery of tartrazine to improve optical clearing and stabilizes its interaction with a photosensitizer. Optical clearing increases the penetration depth of visible light into skin,
