A facile green approach of ZnO NRs synthesized via Ricinus communis L. leaf extract for Biological activities.

In this present work, Zinc oxide (ZnO) nanorods (NRs) were synthesized by bio-mediated approach. The Ricinus communis L. leaf extract act as reducing as well as capping agent for the synthesize of ZnO NRs. The crystalline nature and phase purity of the as prepared ZnO NRs were identified by the Powder X-ray Diffraction (PXRD) studies. The formation of ZnO NRs was determined by the optical analysis. The morphological studies of the synthesized materials were identified by the Field Emission Scanning Electron Microscopy (FESEM) analysis. In this investigation, the antibacterial activity of ZnO NRs were tested against both Gram positive (Staphylococcus aureus, Bacillus subtilis) and Gram negative (Salmonella paratyphi, Escherichia coli) bacteria by agar disc diffusion method. In addition, the green synthesized ZnO NRs exhibits excellent antimicrobial activity than the chemically synthesized method.
