INDIANAPOLIS - Masks are currently part of our daily lives, but these facial coverings aren’t stopping coronavirus particles from passing through, say researchers at IUPUI. The viral particles are too small for masks to capture, but the team says it has developed a solution that deploys the power of copper—at a microscopic scale—to not only trap the virus particles, but also kill them. Applicable for both masks and air filters in high demand for hospitals and schools, the technology has given birth to a startup that the team says could soon ink commercial agreements.
