Investigations on anticancer and antibacterial activities of zinc oxide nanoparticles

A facile and economical precipitation method was adopted to synthesise zinc oxide nanoparticles. The crystallography and optical properties of  as synthesised nanoparticles were studied using X-ray diffraction, UV-Visible spectroscopy, Fourier transform infrared spectroscopy and the morphology of the nanoparticles were revealed via Scanning electron microscopy. The as synthesized nanoparticles were found to be remarkable in inhibiting both gram positive and gram negative pathogenic bacteria. The anticancer activity reveals the dose dependent influence of zinc oxide nanoparticles against human breast cancer cell line (MCF-7). The synthesized nanoparticles were proved to exhibit excellent cytotoxic effect on breast cancer cell line.
