BC researchers develop material sterilization methods using visible light

By: Yelin Gemma Lee, News Writer Researchers from SFU and the University of Victoria (UVIC) have developed a method to sterilize non-woven polypropylene materials using visible light. These materials are commonly found filtering personal protective equipment (PPE) used largely in healthcare settings such as single-use medical masks and respirators.  The Peak spoke to Tyler Cuthbert, who led this study when he was a post-doctoral fellow at SFU school of engineering science.  “We were able to take something called a photosensitizer, which can convert visible light into [a molecule] called reactive oxygen species, and we were able to put this specific molecule…
