The history of colour is fascinating from a social and artistic viewpoint because it shows the way; use; importance acquired. use colours date back to Stone Age (the first news cave paintings); has contributed symbolic development civilizations. Colour been associated with hierarchy; power leadership in some them. advent synthetic dyes revolutionized industry; due their low cost; spread different industrial sectors. Although percentage coloured wastewater discharged by textile; food; pharmaceutical; cosmetic; paper industries; among other productive areas; are unknown; toxic effect ecological implications this into water bodies harmful. This review briefly surrounding discovery natural dyes. We summarise environmental impact caused discharge untreated or poorly treated bodies; which led physical; chemical biological treatments reduce units so as important physicochemical parameters. also focus on laccase utility (EC 1.10.3.2), for discolouration enzymatic treatment wastewater, before its bodies. Laccases (p-diphenol: oxidoreductase dioxide) multicopper enzymes widely distributed plants, insects, bacteria, fungi.

Toward Selective Oxidation of Contaminants in Aqueous Systems

Environmental Science & Technology, Journal Year: 2021, Volume and Issue: 55(21), P. 14494 - 14514

The presence of diverse pollutants in water has been threating human health and aquatic ecosystems on a global scale. For more than century, chemical oxidation using strongly oxidizing species was one the most effective technologies to destruct ensure safe clean supply. However, removal increasing amount with higher structural complexity, especially emerging micropollutants trace concentrations complicated matrix, requires excessive dosage oxidant and/or energy input, resulting low cost-effectiveness possible secondary pollution. Consequently, it is practical significance but scientifically challenging achieve selective interest for decontamination. Currently, there are variety examples concerning aqueous systems. systematic understanding relationship between origin selectivity its applicable treatment scenarios, as well rational design catalyst catalytic oxidation, still lacking. In this critical review, we summarize state-of-the-art strategies decontamination probe origins selectivity, that is, from reactivity either oxidants or target pollutants, arising accessibility via adsorption size exclusion, due interfacial electron transfer process enzymatic oxidation. Finally, challenges perspectives briefly outlined stimulate future discussion decontamination, particularly toward application real scenarios.

Bioinspired Coassembly of Copper Ions and Nicotinamide Adenine Dinucleotides for Single-Site Nanozyme with Dual Catalytic Functions

Analytical Chemistry, Journal Year: 2023, Volume and Issue: 95(5), P. 2865 - 2873

Published: Jan. 24, 2023

Nanozymes can imitate the catalytic properties of natural enzymes while overcoming limitations such as high cost, poor robustness, and difficulty in recycling. However, rational design facile preparation nanozymes are still demand. Inspired by chemical structure laccase, we report an amorphous metal-organic coordination nanocomposite named CuNAD, which is composed copper ions nicotinamide adenine dinucleotide (NAD+) via a simple coordinating coassembly process. As single-site nanozyme, CuNAD exhibits excellent robustness under extreme conditions, significantly stronger activity for phenolic compounds, 4.02-fold higher sensitivity epinephrine detection than laccase. Furthermore, breaking through functional constraints also able to activate H2O2 at neutral pH, benefiting one-step chromogenic platform cholesterol. This approach demonstrates potential develop biomimicking may boost more insights into structure-function relationship nanozymes.
