Duchsnea indica plant extract mediated synthesis of copper oxide nanomaterials for antimicrobial activity and free-radical scavenging assay

Biogenic Copper Oxide Nanoparticles Synthesized from Whole Plant Extract of Nicotiana plumbaginifolia Viv.: Characterization, Antibacterial, and Antioxidant Properties

“…Remarkably, at a 100 µL concentration of CuO NPs, robust antimicrobial activity is evident only against E. coli and S. aureus, with S. aureus, demonstrating significant activity even at 25 µL and 50 µL concentrations (Table 1). In the past, many workers have carried out the antimicrobial activities from different plant-mediated extract-based synthesized copper oxide nanoparticles (51)(52)(53)(54)(55).…”

Procedure Optimization for Green Synthesis of Magnetic‐Copper Nanoparticles by Aqueous Alcea Medicinal Plant Extract and Their Photocatalytic Properties

“…Of course, reducing the antimicrobial effect is also possible if a combination of two antimicrobial agents. [36] Antimicrobial chemicals that are identical in the two groups and have similar antimicrobial mechanisms may have a combined antimicrobial effect, whereas antimicrobial agents with different antimicrobial mechanisms differ in location. Are different from each other, enhance or reduce the antimicrobial effect of each other in the combined state.…”

“…So far, a comprehensive study on the combination of metal nanoparticles with each other and their antimicrobial effect against a wide range of bacteria has not been reported, so further studies in this field seems necessary. Given that the use of nanoparticles to control bacteria is increasing today [36,40] and the antimicrobial properties of zinc oxide and copper oxide nanoparticles have been confirmed in some studies [36,40,41] and also so far Microbial resistance has not been reported to any of them, so using them to control bacteria can be considered as much as possible and using the combined state of these two nanoparticles to achieve synergistic properties seems reasonable. Stephanie et al [42] reported in their study that copper oxide nanoparticles are capable of producing reactive oxygen species (ROS) such as hydrogen peroxide in epithelial cells and inhibit the implementation of cellular antioxidant defense mechanisms.…”

“…The synergistic property of nanoparticles can reduce the need for high concentrations of antimicrobial agents to control the growth of microorganisms and thus reduce the side effects of using high doses. [36,44] The advantages of the green method such as lower cost, higher speed, high production scale and no threat to the environment have made more attention to the production of metal nanoparticles with this method more than other methods. So far, the potential of producing different nanoparticles biologically using bacteria, fungi [45] and plants has been proven in various studies.…”

Green Procedure for the synthesis of Copper Nanoparticles using Nerium oleander Leaf Extract: Characterizations and Applications

“…In the literature, various plant extractmediated Cu-NPs synthesis processes have been described. Leaf extracts of many plants, including Tecoma castanifolia, Duchsnea indica, Psidium guajava, Camellia sinensis, Solanum marginatum, Tamarix gallica, Polyalthia longifolia, Syzygium alternifolium, Suaeda maritime, Artemisia deserti, Juglans regia, Leucas aspera, Achillea nobilis, and Muntingia calabura have been utilized for forming Cu-NPs [8][9][10][11][12][13][14][15][16][17][18][19][20][21] . In keeping with the earlier research, we employed an extract of fresh Nerium oleander leaves as a capping agent and a bioreductant to produce Cu-NPs using this environmentally friendly method.…”
