America: Researchers in America have prepared such a layer, which will kill bacteria in minutes

Scientists in the US have developed a coating that can kill pathogens, including the COVID-19 virus, E. coli and MRSA bacteria, in minutes. The layer, developed by University of Michigan researchers, killed 99.9 percent of germs. University of Michigan professor Anish Tuteja said the layer could be used in public places such as airports and hospitals, which could prove to be a game changer.

Kills bacteria in two minutes

Tuteja said, 'Disinfectant cleaners can kill germs in just a minute or two, but they are quickly destroyed and bacteria can breed on surfaces again.' We have long-lasting antibacterial surfaces based on metals like copper and zinc, but they take hours to kill bacteria, he said. The researchers said the coating can be brushed or sprayed on. These work in less than two minutes.

Coating deemed safe

"The antimicrobials we tested have been recognized by the FDA as safe," Tuteja said. He said polyurethane is a safe and commonly used coating. But we did this test just to be sure, and we found that our particular combination of ingredients is safer than many antimicrobial drugs today.

"Our goal is not just to develop a one-time layer, but to scale it up," Tuteja said. He said that if we can understand those properties, we can develop layers to meet the needs of specific applications.
