Antiviral nano-coatings

•Recently, the Department of Science and Technology (DST) has approved the use of antiviral nano-coatings on anti-Covid-19 masks.
•The antiviral nano-coating has been developed using N9 blue silver which will be modified to form nanocomplexes with Zinc (Zn, atomic number-30) compounds to achieve a synergistic effect. Subsequently, it will be applied as coatings on facemasks and other Personal Protection Equipment (PPEs).
•Nano-coatings have 99.99% effectiveness and these can work on multiple levels at the same time like antiviral, bacterial and fungal and self-cleaning.
•These can be applied to various surfaces such as glass, metal, stone, textiles and plastics by spraying or dipping.
