ZnO nanoparticles and their properties as surface coating materials against coronavirus: viewpoint

Abstract

A pandemic of coronavirus infection is causing a significant public health hazard globally, putting millions of people at risk in an increasing amount of countries. Nanostructured materials have been recognized to be highly efficient against coronaviruses. ZnO nanoparticles possess unique features that enable to act as anti-bacterial and anti-viral. Hence, the aim of the current investigation is to produce zinc oxide nanoparticles and utilized as surface coating materials against COVID-19. Thermal decomposition has been utilized in this investigation to fabricate ZnO nanoparticles with crystallite of 41 and 55 nm. The study outcomes demonstrated that Zinc nanoparticles is a favorable material for future usage as an anti-coronavirus surface due to their ecologically friendly features and exceptional physical and chemical functionality.

Antiviral Activity of Zinc Oxide Nanoparticles against SARS-CoV-2

“…The antiviral activity of ZnO-NPs on SARS-CoV-2 was already shown with VeroE6 cells, reporting severe damage to the viral envelope by free radicals causing oxidative stress to SARS-CoV-2 [29]. Reactive oxygen species (ROS) generated through photocatalysis can destroy proteins, lipids, carbohydrates and nucleic acids, ultimately leading to viral inactivation [37].…”

Congo red pigment weeding out from water media via RuO2@ZnO nanostructure

“…Scientists recently put a great deal of emphasis on metallic nanoparticles and heterostructured nanopowder of appropriate shape and size because of their superior properties and capabilities in absorbing dyes effluent [21]. In recent studies, it was shown that metallic oxides with high activity and surface area are highly effective sorbents for the treatment of waste water [22].The design of nanoscale subistances have been manifctured by means of differants physical,chemical ,mechnical and biological routes [23,24].Several nanoparticles and nanocomposites such as MgO ,TiO 2 ,ZnO , TiO/V 2 O 5 , MgO/Se and MgO@ g-C 3 N 4 were employed to eliminate Cango red dye and other organic dyes from aqueous media [25][26][27][28][29][30].…”
