Biomimetic Synthesis of CuO Nanoparticle using Capparis decidua and their Antibacterial Activity

In this study, a simple approach for the biomimetic synthesis of copper oxide nanoparticle (CuO NP) using Capparis decidua bark extract (CDBE) was investigated. The biogenic synthesis of CuO NP was explored by XRD, SEM, EDX and TEM studies. XRD data shows the formation of monoclinic crystalline structures of CDBE mediated CuO NP. SEM images show that the NPs have quasi-spherical shape and the mean diameter were found to be 5-40 nm. These perceptions were affirmed by HRTEM analysis. CDBE mediated CuO NP shows significant bactericidal performance against three pathogenic bacteria such as Bacillus subtilis, Staphylococcus aureus and Escherichia coli. The study reveals a straightforward, eco-benign and vigorous approach for the biomimetic production of CuO NP using therapeutic plants.
