Pomegranate Juice-Mediated Green Synthesis of Copper Nanoparticles and Evaluation of Their Antimicrobial Activity

In this study , we successfully synthesized copper nanoparticles(CuNPs) using one-step ,eco-friendly and cost effective green synthesis method. The bio-components present in punica granatum (pomegranate ) juice  served as excellent reducing and stabilisng agent during the synthesis process. The UV-Vis and  XRD analysis confirmed the high purity and cubic crystal structure of the CUNPs phase, with a crystalline size of 46.39 nm and it is in agreement with SEM morphology. The green-syntheised CuNps reveal cubic crystal clusters with different lattice constants. The biosynthesized route is more important than the chemically because it offers a new means for researchers to produce cost-effective ,highly active sites with high purity, non-toxic,eco-friendly and have low energy consumption. These efforts will definitely facilitate the translation of synthesis of CuNPs from the laboaratory scale to large –scale industrial production with the goal of benefitting human health and for sustain the protection of environment with chemicals.  The absorption phenomenon in copper nanoparticles, due to surface plasmon resonance is found to be, prominent at about 220 and 232.5 nm .The XRD indicated the presence of CuNPs with significant peaks at [111]. EDX shows the elemental composition is above 80% in the sample. Through antimicrobial activity CuNPs have explored the long term mechanism in antimicrobial efficacy which would open up new avenues in the field of nanomedicine.
