The study was made possible through a grant from Centro2020 of PT2020 (European Regional Development Fund, Fotovid project n. 49708) to LaserLeap Technologies, a partner in this study.\n Key findings from the study reconfirmed that a single dose of photodisinfection is capable of destroying both the SARS-CoV-2 viral spike and viral genome, reducing viral load to below detection limit within five minutes. In addition, the photodisinfection treatment was found to inhibit SARS-CoV-2 infectivity in mammalian cell culture by 99.99%, inactivating the virus with minimal toxicity to the mammalian cells.\n Principal investigator and President of the International Photodynamic Association (IPA), Professor Luis Arnaut, commented: \"Our results show that photodisinfection with methylene blue is highly effective against in vitro isolates of SARS-CoV-2. The non-toxic nature of the treatment would also make it possible to provide safe, fast, and efficient nasal photodisinfection of COVID-19 patients. These strong results support the clinical trial work being conducted at the University of Navarra in Spain which is evaluating the efficacy of nasal photodisinfection to affect the disease progression of COVID-19.\"\n The Steriwave™ photodisinfection laser technology used for the study was developed by Ondine Biomedical. The photodisinfection process works by the light exciting a photosensitive gel, causing an oxidative burst that rapidly destroys pathogens - bacteria, viruses, and fungi - by irreparably damaging...
