Hospital News: Light kills. SARS-CoV-2, That Is.
Note: This article was originally published by Hospital News on February 25, 2021 featuring world-class chemist and Singletto advisor Dr. Belinda Heyne on the perpetual decontamination ability of Light-Activated Dyes..
A new, safe, and affordable SARS-CoV-2 decontamination method has been identified and is now being commercially tested and developed for masks and Personal Protective Equipment (PPE). This method works perpetually, even while a mask is being worn.
This novel decontamination method relies solely on protective dyes, indoor light, and ever-present oxygen.
The DeMaND study co-authored by 52 researchers worldwide with support from 13 labs and institutions, including the WHO, AHS, CDC, University of Calgary, University of Alberta, Québec-Université Laval, Stanford, and the University of Washington, was recently pre-published. For the first time, Methylene Blue (MB), a Light-Activated Dye was shown to inactivate SARS-CoV-2 on a variety of commonly used masks while keeping their integrity.
This Light-Activated Dye, when applied to coronavirus-infected masks, consistently decontaminated SARS-CoV-2 from the masks within 30 minutes and in many cases in less than five minutes.
Further, masks pre-treated with Methylene Blue provided ongoing decontamination once exposed to SARS-CoV-2.
