LESA researchers in collaboration with the Center for Biotechnology & Interdisciplinary (CBIS) at Rensselaer, developed a new device for making masks reusable in the fight against COVID-19. This project began at the request of longtime research partners at Mount Sinai. As the pandemic worsened in New York City, and the shortage of PPE deepened, they asked if Rensselaer could develop a way to make critical resources last longer without losing their effectiveness. The speed with which the Rensselaer team devised and built this solution expedites the possibility that it will be helpful in the fight against the pandemic. A design and construction process that often takes months, or even years, was completed in a matter of weeks.
