Covid killer
The Vancouver-based company has developed antimicrobial technology – called “photodisinfection” – it claims can “rapidly destroy pathogens” in respiratory tracts, including SARS-CoV-2.
A key selling point is that it does this without use of antibiotics.
Its core product, Steriwave, which removes pathogens from the nose to reduce healthcare-acquired infections, is already in use in some Canadian hospitals.
Ondine Biomedical is currently conducting clinical trials seeking regulatory approval to launch Steriwave in the US.
