SINGAPORE (The Straits Times/ANN): Scientists from the Nanyang Technological University (NTU) have developed a reusable mask that is able to kill bacteria droplets within 45 seconds and filter 99.9 per cent of bacteria, viruses and haze particles - better than the medical-grade N95 masks used in hospitals.
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.

Remember To Still Keep A Mask With You
I didn t enjoy wearing a mask, but I did it because I felt there was a chance it was making a difference in the lives of others. Did it make a difference? I don t know, I m not a doctor. I personally didn t feel like it was a control thing like many did, but if there was a chance it helped even a little, I feel like it was worth it.

At the end of the day, I wasn t working in health care and didn t have to wear one like those workers did, and like many still do. So in reality, my days of mask wearing could have been a lot worse. I m fully vaccinated now, and I haven t been bringing a mask with me anywhere. I basically just stopped, especially since once Minnesota announced lessened restrictions, most places put up the mask optional signs.
