Biosynthesis, Characterization and Biological Studies of Copper Nanoparticles from Methanolic Extract of Bulb of Zephyranthes citrina

This work reports the biosynthesis, characterization and biological studies of copper oxide nanoparticles using a methanolic extract of bulb of Zephyranthes citrina. The synthesised copper oxide nanoparticles were characterized by using various spectral techniques. The functional, structural and morphological studies were confirmed by FT-IR, XRD and SEM respectively. The elemental composition was determined by EDAX analysis. The various spectral data confirms the formation of copper oxide nanoparticles and is found to be orthorhombic, 18-50 nm of size and spherical in shape. The synthesised copper oxide nanoparticles were investigated for antibacterial activity against gram positive (Staphylococcus aureus, Bacillus subtilis and Staphylococcus epidermidis), gram negative (Salmonella typhi, Escherichia coli and Klebseilla pneumoniae) and antifungal (Aspergillus niger, Candida albicans and Fusarium oxysporum) activities with different pathogens. The results revealed that copper oxide nanoparticles exhibit excellent inhibition efficiency against representative microorganisms. The outcome of the study could be useful for the development of value added products from indigenous medicinal plants. © 2020 iGlobal Research and Publishing Foundation. All rights reserved.
