RAJKOT: With its broad-spectrum of antimicrobial activity, silver nanoparticles (AgNPs) have proven to be effective in minimizing the risk of transmission of infectious agents, especially airborne viruses including Covid-19, in confined or crowded places like hospitals, public transport, schools, offices, malls and markets, among many others.
Along with several international studies on silver metal coating on disposable facial masks displaying virucidal effect vis-a-vis regular cloth masks, Saurashtra University’s department of physics has also utilized the antibacterial and antifungal behaviour of silver ions and nanoparticles to create a material suitable to combat the coronavirus through face masks.
In its first application, SU made 50,000 masks with silver nanoparticle coating and claims AgNPs can kill 365 pathogens after conducting two successful laboratory tests.
