Surface cleansers use nano-technology to slow-release antiviral agent
PARENTS and care workers are using a new type of hygiene wipe that can protect a mobile phone touchscreen from coronavirus for seven days.
The surface cleansers leave behind an invisible nano-coating that slowly releases an antiviral disinfectant over time.
It means touchscreens and other hard surfaces remain resistant to any droplets they come into contact with which may contain germs or viruses, without the need for constant cleaning.
The hygienic wipes – called ‘Steri-Wipes’ from UK firm LiquidNano – have been given the thumbs up by parents on Mumsnet and praised by NHS staff.
Andy Middleton of LiquidNano said: “Studies have shown that coronavirus can survive for long periods on high contact surfaces such as mobile phones, self-service kiosks, and various types of handle. Our Steri-Wipes were developed using nano-technology in order to create an antimicrobial coating that can protect any hard surface for seven days.”
The innovative wipes have been donated to a number of NHS staff and charity workers in order to help them keep their mobile phones clean. They are also popular on Mumsnet.
One parent wrote: “My children are used to washing their hands but devices which get used a lot, especially phones which are used outside of the house, feel riskier. Having a really easy way to keep them clean is good.”
Steri-Wipes contain a gel to create an invisible film of liquid glass that is 500 times thinner than a human hair, which then kills bacteria and viruses including envelope viruses such as SARS-CoV-2 (which causes Covid-19).
The active ingredient in the wipes is based on a trusted disinfectant called Bacoban, which was developed by a German company and tested by The German Society for Hygiene and Microbiology (DGHM) in Hanover.
A study by the Commonwealth Scientific and Industrial Research Organisation in Australia in October 2020 warned that SARS-CoV-2 could survive for hard surfaces for up to 28 days. A previous study by the University of Arizona in 2012, found that mobile phones can contain up to ten times more bacteria than a toilet seat.
