TL;DR: In this paper , the authors used Canthium coromandelicum leaves to synthesize the copper oxide nanoparticles (CuONPs) in a cost-effective, easy, and sustainable approach.
Abstract: The present study focused to synthesize the copper oxide nanoparticles (CuONPs) using novel Canthium coromandelicum leaves in a cost-effective, easy, and sustainable approach. The obtained Canthium coromandelicum-copper oxide nanoparticles (CC-CuONPs) were characterized using UV-Visible spectroscopy, FT-IR analysis, FESEM, HR-TEM imaging, and XRD study. The XRD pattern verified the development of crystalline CC-CuONPs with an average size of 33 nm. The biosynthesized CC-CuONPs were roughly spherical, according to HR-TEM and FESEM analyses. FT-IR research verified the existence of functional groups involved in CC-CuONPs production. Cu and O2 have high-energy signals of 78.32% and 12.78%, respectively, according to data from EDX. The photocatalytic evaluation showed that synthesized CC-CuONPs have the efficiency of degrading methylene blue (MB) and methyl orange (MO) by 91.32%, 89.35% respectively. The findings showed that biosynthesized CC-CuONPs might effectively remove contaminants in an environmentally acceptable manner.

TL;DR: In this article, the basic principles or mechanisms of green synthesis especially for metal or metal oxide (i.e., ZnO, Au, Ag, and TiO2, Fe, Fe2O3, Cu, CuO, Co) nanoparticles are summarized.
Abstract: Nanotechnology emerged as a scientific innovation in the 21st century. Metallic nanoparticles (metal or metal oxide nanoparticles) have attained remarkable popularity due to their interesting biological, physical, chemical, magnetic, and optical properties. Metal-based nanoparticles can be prepared by utilizing different biological, physical, and chemical methods. The biological method is preferred as it provides a green, simple, facile, ecofriendly, rapid, and cost-effective route for the green synthesis of nanoparticles. Plants have complex phytochemical constituents such as carbohydrates, amino acids, phenolics, flavonoids, terpenoids, and proteins, which can behave as reducing and stabilizing agents. However, the mechanism of green synthesis by using plants is still highly debatable. In this report, we summarized basic principles or mechanisms of green synthesis especially for metal or metal oxide (i.e., ZnO, Au, Ag, and TiO2, Fe, Fe2O3, Cu, CuO, Co) nanoparticles. Finally, we explored the medical applications of plant-based nanoparticles in terms of antibacterial, antifungal, and anticancer activity.

TL;DR: A review literature focusing on the current state of green synthesis of copper and copper oxide (Cu/CuO)-based nanomaterial utilizing plant extracts as reducing and capping agents, and the antimicrobial applications of these biomaterials was proposed as mentioned in this paper .
Abstract: This review literature focuses on the current state of green synthesis of copper and copper oxide (Cu/CuO)-based nanomaterial utilizing plant extracts as reducing and capping agents, and the paper discusses the antimicrobial applications of these biomaterials. Additionally, a novel hypothetical mechanism for the antimicrobial activity of biosynthesized Cu/CuO nanomaterial was proposed. This study will shed light on the future of the green production of Cu/CuO nanomaterial in antimicrobials. This review discusses the synthesis approach and the plant parts that have been utilized previously, allowing researchers to gain a brief understanding of the synthesis procedure employing plant extracts. Moreover, this paper includes an overview of the various analytical approaches used to characterize the produced nanomaterials and a summary of the microbial strains used in this area that have been studied thus far. Finally, the paper discusses the difficulties and potential prospectives associated with the synthesis of Cu/CuO nanomaterials from plant extracts. • Green synthesis of Copper and Copper oxide (Cu/CuO)-based nanomaterials utilizing plant extracts is reviewed. • The optimization parameters in the green synthesis method using plant extracts are elaborated. • Different characterization techniques have been discussed. • A broad literature review of Cu/CuO-based nanomaterials in antimicrobial application. • The mechanism of antimicrobial property was discussed.
