405nm = near UV = can kill germs and virus?

[Xquantumtheory2019]

405 is still incable of killing anything , but your eyes when it's in laser form. You'd need under 350nm of UV for it to start disinfecting.

I know this is an old post but here is a link to a case study that shows promising evidence of 405 nm culminated light as a means to kill bacteria and fungi

Antibacterial and Antifungal Effect of 405 nm Monochromatic Laser on Endodontopathogenic Microorganisms

The purpose of this study is to evaluate the usefulness of 405 nm monochromatic laser irradiation as an alternative management for prevention and/or treatment of endodontic infections. A monochromatic laser-emitting device equipped with a 405-nm laser diode was developed. Using this device, the...
