TAIPEI (The China Post) – Health officials strongly advise disinfecting countertops and other frequently touched surfaces to help contain the coronavirus outbreak.

Amid the pandemic, Hong Kong scientists recently announced a new antiviral coating that could make surfaces virus-proof for up to 90 days.

According to tabloid newspaper The Sun, the coating, called MAP-1, can be sprayed on surfaces frequently used by the public, such as handrails and lift buttons to protect against coronavirus.

Researchers at the Hong Kong University of Science and Technology reportedly spent 10 years developing the coating, which could be a game-changer and drastically reduce coronavirus transmission rates.

The spray-on coating, which costs roughly £7 (NT$260) per coating, boasts millions of nano-capsules containing disinfectants that remain effective in killing bacteria, viruses and spores even after it has dried.

“These places are frequently touched, and, at the same time, serve as a very effective medium for the transmission of diseases,” one of the chief researchers, Professor Joseph Kwan, told The Sun.

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.

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.
