Cytotoxicity of zinc oxide nanoparticles coupled with folic acid and polyethylene glycol

Abstract

The anticancer mediators claim their activity in liquid form as a biocompatible and use in bios stems, which are mostly collected in fluid form. Control on the stability of metal oxide nanoparticles in parallel reducing the effect of large amount on their biological and cytotoxicity activities, remains a challenge. Here anticancer activity and cytotoxicity zinc oxide nanoparticles (NPs) have been presented that are coated with folic acid (F.A) and polyethylene glycol (PEG). The nanoparticles were synthesized by wet chemical method and characterized by x-ray diffraction; scanning electron microscopy and Fourier transform infrared spectroscopy. The cytotoxicity studies were performed on HepG2 cells.MMT assay was used to check the cell viability. The PEG and F.A capped ZnO NPs have shown reduction in cytotoxicity as compare to bare ZnO nanoparticles.
