Washington: Researchers have developed new molecules to prevent the SARS-CoV-2 virus from entering the lungs, which can be sprayed into the nose. The Covid-19 virus enters the body through the lungs when people breathe.
Engineers from John Hopkins University in the US have developed a thread-thin strand of molecules called a supermolecular filament, which is capable of blocking the path of the virus coming in its way. It acts like a swab of filamentous cotton, which absorbs the Covid-19 virus.
