Natural Extracts-mediated Biosynthesis of Zinc Oxide Nanoparticles and Their Multiple Pharmacotherapeutic Perspectives

Abstract: Eco-friendly green syntheses of nanoparticles (NPs) have involved the natural biomass contents since over a decade. The NPs of zinc oxide (ZnO) have important applications in diagnostics, detection of biomolecules, opto-electronic devices, microelectronics like electromagnetic coupled sensor laser devices, neutralization of environmental hazard pollutants as well as pharmaceutical components from water. ZnO-NPs play a pivotal role in drug delivery, exhibiting biomedical activities, such as anti-pathogenics, diagnosis of various diseases, anti-oxidants etc. The interest in synthesizing ZnO-NPs via the biological method (plant extracts) has increased considerably in the last few decades. The development of this new approach and the significant interest in it are mainly related to the absence of toxic chemicals or high-energy applied methods to the biological synthesis which develop more environmentally friendly and cost-effective methods. This review article focuses on recent (January 2020 to May 2020) plant-mediated green synthetic methods which are highlighted comprehensively in this review article. Keywords: Zinc, Nanoparticles, Natural, Synthesis, Plant, Extract.
