Chennai: A nano-coated filter for healthcare workers treating COVID-19 patients has been developed by researchers at IIT-Madras.
The filter’s coating properties are optimised for efficient removal of sub-micron sized dust particles in the air, a press release from the institute said on Monday.
The nano-coating can be positioned according to the need to enhance surface/depth filtration for healthcare workers or public responders, professor K Arul Prakash of the Department of Applied Mechanics, IIT-Madras, said.(PTI)
