LEDs Light the Way to Coronavirus Disinfection

LEDs are commonly used for sterilization, and in the continued effort to combat the coronavirus pandemic, LEDs can also help inactivate SARS-CoV-2. A team in Pakistan designed far-ultraviolet LEDs at a targeted wavelength of 222 nanometers, chosen both for its ability to inactivate the virus and for being safe on human skin. They based their design on the material aluminum gallium nitride, part of a set of materials called III-nitrides which are efficient, inexpensive, and environmentally friendly.

Engineers design UV sterilization stations to aid healthcare workers during coronavirus pandemic

Engineers at Binghamton University, State University of New York have designed sterilization stations that use ultraviolet light to kill the coronavirus on any contaminated personal protective equipment (PPE) such as N95 masks and face shields.
