Covid-19: IIT Madras develops nano-coated filter for healthcare workers

IIT Madras

At a time when the total number of COVID-19 cases is mounting every passing day with India being third worst affected country in terms of total confirmed cases, scientists across the world are working on various innovative projects to keep COVID-19 at bay.

In India, IITs have played a great role, helping the government in its effort to tide over the corona crisis. As per an India Today report, some researchers from IIT Madras have developed a nano-coated filter media for healthcare workers treating Covid-19 patients

Apart from healthcare, this filter has defence applications as well and other places where air filtration of submicron particles is required.

This pioneering work is funded by Defence Research Development Organisation (DRDO) for defence applications and due to its high potential for the need of the hour, it is repositioned in health care applications, report said.

Prof. K. Arul Prakash, Department of Applied Mechanics, IIT Madras, said, “The nano-coating fabricated through the electrospinning process have fiber diameter less than 1 micron and can be positioned according to the need to enhance surface/depth filtration for healthcare workers or public responders.”

“Nano-coated filter media have much better reverse cleanability behaviour resulting in an extended service life period of air filters providing prolonged working hours for armoured vehicles. This will save a huge cost for defence applications where the filters are currently imported from developed countries,” he further stated about its various application.
