Electrospun CuS nanoparticles/chitosan nanofiber composites for visible and near-infrared light-driven catalytic degradation of antibiotic pollutants

NIR-activated quercetin-based nanogels embedded with CuS nanoclusters for the treatment of drug-resistant biofilms and accelerated chronic wound healing

“…49 The superior antimicrobial response can be ascribed to unique polymeric structures of CNGs that facilitated substantial contact-mediated biofilm disintegration, followed by localized catalytic and NIR-assisted phototherapeutic action. 50…”

Protein Encapsulated Covellite CuS Nanospheres for the Efficient Oxidative Degradation of Organic Dyes in Wastewater

“…Covellite CuS gained much attention because of its additional absorbance band at NIR region and narrow bandwidth which resulted in low potential energy for activation to be used as efficient catalyst. 12 Furthermore, fenton like catalytic activity enables its application in waste water management and act as a good replacement for the iron in Fe-fenton system.…”

“…11 Amongst, crystalline covellite CuS NPs were considered as the prominent material due to its additional absorbance band at NIR region and narrow band width that enables efficient catalytic activity with low potential energy. 12 Their unique optical, electrochemical properties, low toxicity, earth abundant, cheap and cost-effective synthesis extended the growth in various applications such as photothermal ablation, photocatalysis, energy storage, and biosensor application. 13,14 In particular, catalytic efficiency of CuS depends on various factors such as surface area, purity of crystal, morphology etc.…”

Enhanced PMS/O2 activation by self-crosslinked amine-gluteraldehyde/chitosan-Cu biocomposites for efficient degradation of HEPES as biological pollutants and selective allylic oxidation of cyclohexene

“…16,17 Among them, chitosan as a kind of natural polysaccharide derived from N-deacetylation of chitin and being composed of N -acetyl-2-amino-2-deoxy-(α) d -glucopyranose units with β -(1–4) glycosidic linkage would be an appropriate bio matrix for the synthesis of an activator/absorbent to treat contaminated water. 18 Indeed, the large number of reactive functional groups (–OH/–NH 2 ) regularly distributed in chitosan chains makes it the best doping material for oxides of metals and pure metals, and the fabricated chitosan–metal complexes have been applied in various fields such as energy storage, adsorption, antibacterial activity and catalysis. 19…”
