Antimicrobial and antioxidant potentials of biosynthesized colloidal zinc oxide nanoparticles for a fortified cold cream formulation: A potent nanocosmeceutical application. Mater Sci Eng C Mater Biol Appl. 2017 Oct 01;79:581-589 Authors: S S, H LJK, K R, M S Abstract Nanocosmeceuticals are promising applications of nanotechnology in personal care industries. Zinc oxide is an inorganic material that is non-toxic and skin compatible with self-cleansing and microbicidal properties. Herein, exploitation of colloidal zinc oxide nanoparticles (ZnONps) as potent biomaterial for a topical formulation of cosmetic and dermatological significance is employed. ZnONps were green synthesized using environmentally benign Adhatoda vasica leaf extract and characterized by UV-Vis absorption spectroscopy, Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), dynamic light scattering (DLS), high-resolution transmission electron microscopy (HR-TEM) and energy-dispersive X-ray spectroscopy (EDX). The results reveal that the biosynthesized ZnONps exhibit an absorption peak at 352nm. XRD and HR-TEM analyses confirm the hexagonal wurtzite structure of ZnONps with particle size of about 10nm to 12nm. Elemental analysis by EDX confirms the presence of zinc and oxygen. Zeta potential of -24.6mV affirms the stability of nanoparticles. The antibacterial and antifungal activities of biosynthesized ZnONps exhibit mean zone of inhibition from 08....
