Researchers at Hong Kong University of Science and Technology have developed what they call a ‘smart spray’ that protects a range of surfaces including metal, plastic and fabric from coronavirus.
The new disinfectant spray can protect these surfaces from the virus for up to 90 days by making it ‘inactive’.
Researchers say it will be on sale in Hong Kong from next month and will cost just $8.
Called the MAP-1, the disinfectant according to experts lasts ‘significantly longer’ than traditional sprays that use bleach or alcohol.
Unlike diluted bleach and alcohol, MAP-1 is further boosted by heat-sensitive polymers which release disinfectants when touched.
MAP-1 has technology that allows it to release chemicals when someone touches a surface that has been sprayed – rather than have them always available.
It has also been approved for domestic use in Hong Kong and has already been tested in shopping malls, schools, churches and sports halls.
“These places are frequently touched, and, at the same time, serve as a very effective medium for transmission of diseases,” chief researcher Professor Joseph Kwan.
SARS-CoV-2, the virus causing the COVID-19 according to scientists can survive on surfaces for hours and even up to a week.
According to studies the virus can also survive on paper for three hours but will live on surgical face masks for up to seven days.
The Hong Kong researchers say their disinfectant coating can be used to coat nanofibers that are then woven to form surgical masts – providing frontline workers with more protection from COVID-19.
The scientists said it took more than a decade to develop the spray which can also be used on surfaces regularly touched by the public including handrails and buttons.
It is non-toxic and safe for skin and the environment and can be used in hand sanitisers, paints and coating materials.
The researchers also said it can be used in filter materials for air and water purification, as well as clothing and surgical masks to safeguard the health of the individual and public.
