Antiviral innovations will calm our fears with special masks that filter out and kill microbes before you breathe them in, using high technology for sensing and sterilizing.

Material scientists, chemists, biologists, and engineers at Harvard's Wyss Institute are working on a prototype of a high-tech mask that can help detect and kill germs.

This mask is still in testing but has received a lot of global interest. A smart mask against pathogens that target the respiratory system like COVID-19 would greatly reduce concern about the disease.
