Researchers at the Hong Kong University of Science and Technology spent 10 years developing the coating, which could be a game-changer and drastically reduce coronavirus transmission rates.
One of the chief researchers, professor Joseph Kwan, said: “These places are frequently touched, and, at the same time, serve as a very effective medium for transmission of diseases.”
The spray-on coating is created from millions of nano-capsules containing disinfectants that remain effective in killing bacteria, viruses and spores even after it has dried.
PROTECTS FOR MONTHS
Unlike common disinfectants such as bleach or alcohol, MAP-1 disinfects using heat-sensitive particles that activate and kill viruses on human contact.
It is also non-toxic and safe for skin and the environment, researchers said.
Give now to The Sun’s NHS appeal
BRITAIN’s four million NHS staff are on the frontline in the battle against coronavirus.
But while they are helping save lives, who is there to help them?
The Sun has launched an appeal to raise £1MILLION for NHS workers. The Who Cares Wins Appeal aims to get vital support to staff in their hour of need.
We have teamed up with NHS Charities Together in their urgent Covid-19 Appeal to ensure the money gets to exactly who needs it.
The Sun is donating £50,000 and we would like YOU to help us raise a million pounds, to help THEM. No matter how little you can spare, please donate today here: www.thesun.co.uk/whocareswinsappeal.
MAP-1 was approved for official and mass consumer use in February after clinical tests at a Hong Kong hospital and care home earlier this year.
It will go on sale in Hong Kong shops next month and has already been sprayed around the homes of more than a thousand low-income families in the city.
A mother-of-two living in a 110sq ft “coffin” home that was recently sprayed, Law Ha-yu told Sky News: “I feel like it has strengthened our protection against the virus.”
