HKUST team says its new spray kills Covid-19

Researchers at the Hong Kong University of Science and Technology have recognizably developed a long-lasting coating that can be sprayed on various surfaces to kill most bacteria and viruses — including the new novel coronavirus. 

The new coating mentioned above is from GERMAGIC anti-bacterial technology. It has been proven able to kill 99.9 percent of highly-infectious viruses such as measles, mumps, molds and efficiently stop the spreading of such dangerous diseases as Influenza, Mers,… 

The coating can be applied on a wide range of surfaces such as metals, plastics and fabrics, the researchers say.

Professor Yeung King-lun from the Department of Chemical and Biological Engineering said their product continues to be effective for up to three months, unlike traditional disinfectant, containing bleach and alcohol and needs to be re-apply regularly. 

“We use a special type of polymers that are actually used in a lot of food products. We reassemble them in a certain way to make them more effective,” Yeung said. 

The new product has been used in hospitals, schools, daycare centres and elderly homes. It has been utilised in China, Hongkong, Singapore and recently bought to Vietnam.
