and Aim:Emergence of different applications of metallic nanoparticles in various field leads to innovation of new synthetic strategies. Besides being non-toxic to mammalian cells, zinc oxide nanoparticles (ZnONPs) has gained paramount attention due to its excellent antibacterial potential. This study illustrates a comparative analysis of antibacterial and cytotoxic activity of both phytochemically synthesized and chemically synthesized commercially available ZnONPs.
Materials and Methods:As a source of reducing agent, leaf extract of Coriander sativum was employed in case of green synthesis of ZnONPs. Several techniques, such as X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), Dynamic light Scattering (DLS) and Field emission Scanning Electron Microscopy (FESEM) were performed to characterize both green synthesized and commercial ZnONPs.Antibacterial potential of both theZnONPs were investigated on Gram-positive and Gram-negative bacterial strains to draw a correlative outcome. Hepatocellular cell line was used to determine the cytotoxic activity of both ZnONPs.
Results:Both the nanoparticles showed antibacterial and cytotoxic activity with measurable degree of difference.
Conclusion: From these studies it can be concluded, the green synthesized nanoparticles showed greater antibacterial as well as cytotoxic activity in comparison to the commercial ZnONPs.
