| Abstract Scope |
COVID-19 has shaped up to be one of the defining challenges of our lives. It has proven to be such a challenge due to its ability to spread quickly. One of the primary modes of spread is surface to surface contamination. To combat it, we propose a novel antiviral conformal nano-coating on PPE surfaces. UV radiation has traditionally been used as a disinfecting agent. Here we report a Yttrium Orthosilicate-based up-conversion (visible to UV) nanomaterials. Cationic and anionic polymers are used to form the layer by layer (LBL) coating on surfaces sandwiching the active materials. Another method of inactivation of virus involving oligosaccharide species was also grafted to the polymer layer. Y2SiO5(Pr, Gd) has reduced active viral load from 4*104 to 9.28 (more than 99% decrease in active viral load), and Y2SiO5 (Pr, Gd, Li) has reduced viral load from 4*104 to 0 (100%) in an hour. |
