Copper oxide nanoparticles have been received attraction due to their unique properties and potential future applications. In present work nanostructure Copper (II) oxide (CuO) spherical nanoparticle synthesized by solution combustion method and the influence of different fuel and condition on the properties of CuO particle was investigated. Crystalline phase and size indicated by applying XRD and particle size distribution studied further using DLS. Scanning electron microscopy (SEM) was used for morphological study and EDAX analysis shows composition of CuO particles. Nanostructure of copper (II) oxide particle studied further by Transmission electron microscopy (TEM) and selected area electron diffraction (SAED) applied for detail study on crystalline structure of particles.

The development of green technology is creating great interest for researchers towards low-cost and environmentally friendly methods for the synthesis of nanoparticles. Copper oxide nanoparticles (CuO-NPs) attracted many researchers due to their electric, catalytic, optical, textile, photonic, monofluid, and pharmacological activities that depend on the shape and size of the nanoparticles. This investigation aims copper oxide nanoparticles synthesis using Aerva javanica plant leaf extract. Characterization of copper oxide nanoparticles synthesized by green route was performed by three different techniques: X-Ray Diffraction (XRD), Fourier Transform Infrared (FTIR) Spectroscopy, and Scanning Electron Microscopy (SEM). X-ray diffraction (XRD) reveals the crystalline morphology of CuO-NPs and the average crystal size obtained is 15 nm. SEM images showed the spherical nature of the particles and size is lying in the 15–23 nm range. FTIR analysis confirms the functional groups of active components present in the extract which are responsible for reducing and capping agents for the synthesis of CuO-NPs. The synthesized CuO-NPs were studied for their antimicrobial potential against different bacterial as well as fungal pathogens. The results indicated that CuO-NPs show maximum antimicrobial activities against all the selected bacterial and fungal pathogens. Antimicrobial activities of copper oxide nanoparticles were compared with standard drugs Norfloxacin and amphotericin B antibiotics. Minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) of copper oxide nanoparticles were 128 μg/mL against all selected bacterial pathogens. MIC of fungus and minimum fungicidal concentration (MFC) of CuO-NPs were 160 μg/mL. Thus, CuO-NPs can be utilized as a broad-spectrum antimicrobial agent. The cytotoxic activity of the synthesized CuO-NPs suggested that toxicity was negligible at concentrations below 60 μg/mL.

There are many methods to synthesize metal and metal oxide nanoparticles. In this paper, copper oxide nanoparticles have been synthesized by solution combustion method using Brassia actinophylla i.e. Schefflera actinophylla flower extract belongs to Araliaceae family. The importance of solution combustion is one of the easy and simplest methods for the synthesis of metal oxide nanoparticle. The CuO nanoparticles were synthesized at various temperatures and the characterization has been carried out by UV, FTIR, PXRD, SEM, TEM and EDAX analysis. At lower temperature, the peak was not observed but at 400 ºC, the UV peak was observed at 340 nm. The FTIR peaks observed at 1000-500 cm-1 confirms again the presence of CuO nanoparticles. The monoclinic phase and crystalline structure of nanoparticles were revealed by PXRD pattern, by Scherrer′s method the average crystalline sizes were found to be in the range of 15 to 24 nm. The size and the shape of nanoparticles were confirmed by SEM and TEM reports. The SEM images of nanoparticles show spherical in shape and free from agglomeration. TEM analysis reports the nanoparticle sizes ranging from 2 to 20 nm. The percentage of copper (52 %) and oxygen (26 %) elements were recorded in the EDAX analysis. The study of size and stability of nanoparticles were done by zeta potential values. The antibacterial activity of CuO nanoparticles were carried out against Staphylococcus aureus and Escherichia coli bacteria's by agar well diffusion method. The MTT assay was performed in order to check the anticancer activity of CuO nanoparticles against HT-29 colon cancer cells.
