Nanoparticle Coating Material to Tackle Coronavirus

IIT Madras startup is creating nanoparticle coating material to tackle coronavirus. The coatings are expected to be effective up to 60 wash cycles, thereby making the textiles re-usable.

Novel and scalable methods for coating textiles with nanoparticles-based antimicrobial agents that can inactivate the human coronavirus on contact are being developed by an Indian Institute of Technology (IIT) Madras-incubated startup Muse Wearables.

The coated textiles can be primarily used to manufacture N95 masks, surgical masks, Personal Protective Equipment (PPE) and food packaging bags, among others, with inherent properties of inactivating the virus.

Coronavirus
Coronaviruses infect animals, humans, and birds. Human coronaviruses, such as SARS, MERS, and 2019-nCoV cause respiratory distress and even death. The S protein is the infectious agent of the virus.

‘New nanoparticle coating material to tackle coronavirus is being created by IIT Madras.’

According to the Institute, Muse Wearables' current pilot machine can coat textiles of length up to 100 metres within a few minutes, thereby making it a viable commercial solution that can be deployed immediately.

Muse Wearables was incubated by IIT Madras Incubation Cell.

"They have quickly mobilized and repurposed their offerings in response to the situation and are striving to make a positive contribution to the nation's anti-virus efforts," Dr Tamaswati Ghosh, Chief Executive Officer, IIT Madras Incubation Cell, said in a statement.

Coronavirus in Tamil Nadu: 14-Day-Old Baby Among 231 New Cases In TN, Total 2,757
In Tamil Nadu, 231 coronavirus positive cases have been reported, taking the total cases to 2,757, revealed sources.

Some highlights of these nano-particles coated textiles include, anti-microbial properties -- it continuously captures and destroys viruses and other microbes upon contact. Other viruses are as small as 30 nanometres can also be inactivated permanently.

It does not leach while washing in water and is environment-friendly. At present, the particles can be coated on materials like cotton, polyester and cotton ? polyester. More fabrics will be tested soon.

Mobile Phones be Acting as 'Trojan Horses' for Coronavirus
Authors say the virus responsible for COVID-19 -- SARS-CoV-2 -- is probably present on mobile phones and other touch-screen devices of coronavirus sufferers.

It is non-toxic and therefore can be safely used for making masks and other PPEs, the Institute.

Currently, the startup is assembling the coating machine and will shortly commence coating various textiles with different nanoparticle solutions.

New Guidance for Treating Stroke Patients During Coronavirus Pandemic Developed
In an effort to mitigate the spread of COVID-19, scientists are improving ways to treat patients with acute large vessel occlusion strokes in a safe manner that also better protects health care workers.

Their coated textiles are expected to be ready for testing by the first week of May 2020. The start-up is also partnering with a mask manufacturing company to launch five-layered Antiviral N95 Masks at an estimated price of Rs 300 per piece.
