A new disinfectant spray can protect coronavirus surfaces for up to 90 days by & # 39; inactive & # 39; to be made in Hong Kong for sale from just £ 7 next month.

Researchers at the & # 39; Hong Kong University of Science and Technology say that & # 39; & # 39; smart spray & # 39; Works on a variety of surface types, including metal, plastic and dust.

The disinfectant, called MAP-1, lasts & # 39; significantly longer & # 39; then traditional sprays that do not use bleach as alcohol, according to the Hong Kong team.

MAP-1 has technology that allows the chemical to release when someone attacks a surface that is sprayed – instead of always being available.

Researchers at the & # 39; Hong Kong University of Science and Technology say that & # 39; & # 39; smart spray & # 39; Works on a variety of surface types, including metal, plastic and dust. It was used to spray the inside of thousands of homes in poorer neighborhoods of Hong Kong

Tiny nano fibers were sprayed with the chemical and then used to make surgical masks that were more resistant to COVID-19

The disinfectant, which is tested in shopping centers, schools, churches and sports halls, is approved for domestic use in Hong Kong.

SARS-CoV-2, the virus that causes the COVID-19 pandemic that destroys the world, can survive for hours to a week, researchers say.

Studies show that the virus can survive for three hours on paper, but will live on surgical face masks for up to seven days.

The Hong Kong team says its disinfectant coating can be used to coat nanofibers that will then be woven to form surgical masts – and frontline workers provide more protection against COVID-19.

Coronavirus can live on different surfaces for a different amount of time - it takes 7 days on a surgical mask, just 3 hours on paper. According to a developer, the new disinfectant MAP-1 is working on a range of materials. The data is from the New England Journal of Medicine

It took over a decade to develop the spray and can also be used on surfaces that are not regularly touched by the public, including handrails and buttons.

& # 39; These sites are often touched upon, and at the same time serve as a highly effective medium for transmission of diseases, & # 39; said Chief Investigator Professor Joseph Kwan.

The coating that forms after spraying has millions of nano-capsules that contain disinfectants, which Kwan says remains effective in killing bacteria, viruses and spores, even after & # 39; t the coating is dry.

Unlike diluted bleach and alcohol, MAP-1 is given further impetus by heat-sensitive polymers that release disinfectants when they touch.

It is non-toxic and safe for skin and the environment, the researchers say.

This means that it can be used in hand softeners, dyes and coating materials, filter materials for air and water purification, as well as clothing and surgical masks to protect the health of the individual and the public.

It was tested on water pipes that were used in sewage works – they found that the pipes covered with MAP-1 were more resistant to corrosion and microbial contamination.

Following clinical trials this year at a Hong Kong hospital and an elderly home, the coating has been made available for commercial purchase by Germagic, a unit of & # 39; the industrial partner of & # 39; a university, Chiaphua Industries.

With the help of a local charity, the non-toxic coating has already been sprayed around & # 39; homes of over a thousand low-income families in & # 39; e city.

& # 39; I feel it has enhanced our protection against the virus, & # 39; said Law Ha-yu, a mother of two who doesn't live in a 110-square-foot subdivision that was recently sprayed with the coating.

The researchers said that shopping centers, schools and sports training facilities in the city have adopted the coating.

Applying the coating in schools costs £ 2,000 ($ 2,600) to £ 5,180 ($ 6,451), depending on the size of the spray area.

The company also plans to introduce versions of household use of 50ml and 200ml with prices ranging from £ 7.26 to £ 25.

MAP-1 is designed for use on various surfaces, including metals, concrete, wood, glass, plastic, such as fabrics, leather and textiles, without altering the appearance of materials and the tactile feel, the developers claim.

Using a special blend of antimicrobial polymers, the new coating effectively kills up to 99.99 per cent of bacteria and viruses through contact killers and anti-adhesion technology.

It works on Rubella, avian flu, H1N1 and FCV – a non-enveloped virus that's one of the hardest to kill.

According to the 2016 U.S. Environmental Protection Agency guidelines, effective against FCV is equivalent to inactivating the coronavirus.
