Emilia sonchifolia leaf extract-mediated green synthesis, characterization, in vitro biological activities, photocatalytic degradation and in vivo Danio rerio embryo toxicity of copper nanoparticles

Abstract

Green-synthesised Cu nanoparticles were examined, and investigations were conducted on the photocatalytic activity of the nanoparticles for the degradation of methylene blue. The Cu nanoparticles were determined in vitro and in vivo biological activities to be significant.

Biological Synthesis of Copper Nanoparticles Using Edible Plant Allium monanthum: Characterization of Antibacterial, Antioxidant, and Anti-Inflammatory Properties Using In Silico Molecular Docking Analysis

“…Figure 2d shows the FT-IR spectra of biosynthesized AM-CuNPs and the A. monanthum extract. The FT-IR spectrum results revealed broadband peaks in the 3400-2400 cm −1 a b d c 220) and (222) planes, respectively, which are a perfect match with copper NPs [29]. In addition, the sharp intense peaks strongly supported the formation of copper NPs with an extremely crystalline nature, having values similar to the fcc cubic phases.…”

“…Hence, the peak positions were consistent with the metallic copper of a crystalline nature reported earlier. Recently, Narayanan et al reported strong peaks at 2θ = 32.1 • , 35.2 • , 39.5 • , 49.5 • , 53.2 • , 62.3 • , 67.2 • , 68.5 • and 75.2 • , corresponding to the (100), (002), (111), (202), (020), (113), (311), (220) and (222) planes, respectively, which are a perfect match with copper NPs[29]. In addition, the sharp intense peaks strongly supported the formation of copper NPs with an extremely crystalline nature, having values similar to the fcc cubic phases.…”
