N95 masks are able to prevent around 95 per cent of aerosolised droplets and particulate matter of around 0.3 microns in size from entering them. The filter of the NTU-developed mask is coated with a layer of copper oxide nanoparticles, which damage the DNA of important cell structures in the bacteria, causing them to die, said Professor Lam Yeng Ming, chair of NTU s School of Materials Science and Engineering, who developed the antimicrobial coating. ....
