Abstract: 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.

To synthesise Copper oxide nanoparticles and study it's characterisation using UV -viz - Spectrophotometer and TEM.  Copper oxide nanoparticles are eco-friendly, cost-efficient and diverse utilisation all over the medical field. The shape of the CuO nanoparticles are spherical, and its characterisation is done using SEM, TEM, and UV-vis techniques. The size of the nanoparticles mediated in each plant extract differs from one another. MATERIALS AND METHODS  * Collection and Preparation of Plant extracts. * Synthesis Of CuONPs * Characterization of copper nanoparticles * preparation of nanoparticles powder. The plant extract is in green colour, and the CuO nanoparticles are seen in light yellowish in colour. Uv-VIS SPECTROMETER:  The particle size ranges from 2-100nm and shape is spherical. The graph reached its peak at the wavelength of 300nm. The TEM shows spherical shape, dispersion and versatile nanoparticles. They appear to be arranged in a cluster, open and quasi-linear superstructures. This research shows that CuO nanoparticles shows excellent biocompatibility. The particles which are smaller in size shows great immunity. Hence the nanoparticles are expected to be used in future for effective drug systems.

Anticancer Activities

Background: Cancer is defined as an abnormal/uncontrolled cell growth that shows rapid cell division. This disease is annually recognized in more than ten million people. Nanomaterials can be used as new strategies for cancer therapy. Nanostructured devices have developed for drug delivery and controlled release and created novel anticancer chemotherapies. Nanomaterials were taken into consideration because of their new properties, containing a large specific surface area and high reactivity. Copper oxide nanoparticles (CuONPs) have potential applications in many fields like heterogeneous catalysis, antibacterial, anticancer, antioxidant, antifungal, antiviral, imaging agents, and drug delivery agents in biomedicine. CuONPs display different physical properties, such as hightemperature superconductivity, electron correlation effects, and spin dynamics. NPs can be synthesized using different methods like physical, chemical, and biological methods. Methods: Copper oxide nanoparticles (CuONPs) have been suggested for its broad usage in biomedical applications. In this review, we tried to exhibit the results of significant anticancer activity of green synthesized CuONPs and their characterization by different analytical techniques such as UV-Vis, FT-IR, XRD, EDAX, DLS, SEM, and TEM. Results: The green method for the synthesis of CuO nanoparticles as eco-friendly, cost-effective, and facile method is the more effective method. Synthesized CuONPs from this method have an appropriate size and shape. The Green synthesized CuONPs exhibited high potential against several breast cancer (AMJ-13, MCF-7, and HBL-100 cell lines), cervical cancer (HeLa), colon cancer (HCT-116), gastric cancer (human adenocarcinoma AGS cell line), lung cancer (A549), leukemia cancer, and other cancers with the main toxicity approach of increasing ROS production. Conclusion: The present review confirms the importance of green synthesized CuO nanoparticles in medical science especially cancer therapy that exhibited high activity against different cancer in both in vitro and in vivo. The main toxicity approach of CuONPs is increasing the production of reactive oxygen species (ROS). It needs to perform more studies about in vivo cancer therapy and following clinical trial testing in the future. We believe that green synthesized CuO nanoparticles can be used for the improvement of different diseases.
