“…In addition, the particles biosynthesized by C. myrica extract were 11-80nm in size and spherical. Our findings are consistent with previous research (Dastjerdi and Montazer, 2010; Abboud et al, 2014;Thamer et al, 2018).…”

Copper oxide nanoparticles (CuONPs) were synthesized by a green method using aqueous extract of Cystoseira myrica as capping and reducing agent. A UV-visible spectrophotometer was used to characterize the produced nanoparticles. The aqueous extract of C. myrica at pH 5 and 100°C after 150 minutes was shown to be the optimal condition for the synthesis of copper oxide nanoparticles. The Structure and characters of synthesized nanoparticles were confirmed using TEM, DLS, XRD, and FTIR. The efficiency of different concentrations of copper oxide nanoparticles (25, 50, 75, 100) µg/ml synthesized from aqueous extract of C. myrica exhibit high antitumor activity against some cancer lines such as HepG2 and MCF-7. The percent of cell viability decreases as the concentration of nanoparticles rises. Copper oxide nanoparticles at a concentration of 100 µg/ml were found to have the lowest percentage of cell viability in HepG2 (18.7%), while MCF-7 was (19.27%).

“…The UV-Vis absorption spectrum of the CuO NPs was analysed by forming a 0.1 wt% dispersion of the product using deionized water. The UV-Vis absorption spectrum (Figure 5a) illustrates a rather broad absorption which peaks at 387 nm and is most probably attributed to surface plasmon resonance (SPR) due to semiconductor excitation of CuO [42]. Using the Tauc plot approach, the band gap energy (E g ) of the CuO NPs was derived with the following equation:…”

In this study, phytochemical assisted nanoparticle synthesis was performed using Muntingia calabura leaf extracts to produce copper oxide nanoparticles (CuO NPs) with interesting morphology. Scanning electron microscope (SEM) and transmission electron microscope (TEM) analysis of the biosynthesized CuO NPs reveal formation of distinct, homogeneous, and uniform sized CuO nanorods structure with thickness and length of around 23 nm and 79 nm, respectively. Based on Fourier-transform infrared (FTIR) analysis, the unique combinations of secondary metabolites such as flavonoid and polyphenols in the plant extract are deduced to be effective capping agents to produce nanoparticles with unique morphologies similar to conventional chemical synthesis. X-ray diffraction (XRD) analysis verified the monoclinical, crystalline structure of the CuO NPs. The phase purity and chemical identity of the product was consolidated via X-Ray photoelectron spectroscopy (XPS) and Raman spectroscopic data which indicate the formation of a single phase CuO without the presence of other impurities. The direct and indirect optical band gap energies of the CuO nanorods were recorded to be 3.65 eV and 1.42 eV.

“…The initial identification of the synthesized copper oxide nanoparticle using Annona muricata stem extract was done by the visual change of the colour of solution from blue to bright green which indicates the presence of copper oxide nanoparticles. [17], [22]. The Annona muricata stem extract does not show any colour change even if it is kept for several weeks until the copper sulphate solution was added to it.…”

Nanotechnology is a rising field of science and technology that deals with the particles having size in the range of 1 to 100 nm. Copper oxide nanoparticles has many properties like antifungal activity, antibacterial activity, optical properties, conductive properties, etc. Due to its demand of diversified use, copper oxide nanoparticles were fabricated using ecofriendly and non-toxic Annona muricata stem extract. The extract with copper sulphate pentahydrate showed gradual change in the colour of the extract from brown to green which indicates the CuO nanoparticles synthesis. The fabrication is followed by characterization of CuO nanoparticles using UV-vis spectroscope, FTIR, XRD and SEM. The characterization showed roughly spherical shaped nanoparticles in the range of 100nm with high crystalline monoclinic phase. FTIR absorption spectra conclude that the compounds attached with copper oxide nanoparticles could be polyphenols with aromatic ring. The CuO nanoparticles exhibited antibacterial activity; it showed the maximum activity against E.coli (18 mm). Keywords: Annona muricata, copper sulphate pentahydrate, FTIR, nanomaterials, SEM, XRD.
