Biomolecule-assisted synthesis of highly stable dispersions of water-soluble copper nanoparticles

Alloyed nanostructures integrated metal-phenolic nanoplatform for synergistic wound disinfection and revascularization

“…High-resolution XPS spectra of Cu 2p indicated the presence of Cu 0 and Cu 2+ at 933.2 and 935.0 eV, respectively ( Fig. 2 E) [ [79] , [80] , [81] ]. Meanwhile, energy dispersive X-ray spectroscopy (EDS) mapping images further confirmed the presence and high distribution of Cu and Ag in the microstructure of Ag@Cu-MPN NC while still retaining the N signal from ZwPEI ( Fig.…”

Facile synthesis of chitosan derivatives and Arthrobacter sp. biomass for the removal of europium(III) ions from aqueous solution through biosorption

“…This thermal instability may be due to the function of amine groups, which aid in the thermal degradation of chitosan, but due to the cross-linked chitosan beads, some of the amine groups participated in crosslinking and thus increased the thermal stability of the chitosan beads in R i (Pawlak and Mucha, 2003). R ii had the highest decomposition rate for the chitosan biosorbents of~0.46 wt%/ o C for both biosorbents and occurred over the range of~260 to~340 C. This was the first stage of the oxidative decomposition of the chitosan skeleton representative of the polymeric backbone and/or chain degradation (Pawlak and Mucha, 2003;Jayakumar et al, 2007;Xiong et al, 2013). During this quintessential stage the possible degradation products are shown in Fig.…”

Copper-Incorporated Collagen/Catechol Film for in Situ Generation of Nitric Oxide

“…Recently published papers have shown the possibility of catechols and copper ions to form copper nanoparticles with size from tens to hundreds nm 42,43 . Briefly, catechol groups were involved both in Cu (II) reduction and nanoparticle surface binding.…”
