A specific wavelength of UV light, known as far-UVC, could be effective at killing methicillin-resistant Staphylococcus aureus (MRSA) bacteria, without damaging the surface of the skin. As infection with drug-resistant pathogens can be a potentially life-threatening complication of surgery, the light therapy could be used to kill these bacteria and improve patient outcomes.

The Columbia researchers previously found that the far-UVC light was just as effective as other, more-damaging UV wavelengths at killing bacterial pathogens like MRSA. They conducted further research using a 3-D cell culture model of human skin, and a hairless mouse model, and found that the far-UVC light was safe for skin exposure.

“Our findings offer a potential practical pathway towards significantly reducing surgical site infection rates without risk to the health and safety of patients and medical personnel,” said Dr. David J. Brenner, lead author of the study. Brenner and his team plan to test the far-UVC light on human patients, and eventually they hope to determine whether the light therapy could be effective at killing airborne pathogens.

Currently, the most effective and safest way to fight against COVID-19 is far uvc 222nm technology. This is a UV-based disinfection method which is based on biophysical principles and a key advantage of the UV-based approach is that UV light is likely to be effective against all airborne microorganisms, in marked contrast to vaccination methods.

For example, while the inactivation efficiency of UV light will almost certainly vary as different strains of influenza virus emerge, they are unlikely to be significant. Similarly, as multidrug-resistant variants of bacteria emerge, their UV inactivation capacity is unlikely to vary greatly.

Care222 is a new disinfecting light source that, even though not harmful to the skin or eyes of humans or animals, deactivates bacteria and viruses in the same manner as conventional ultraviolet sanitizers.

Since far-UV light can pass through and therefore inactivate bacteria and viruses which are usually micrometres or smaller, whereas far-UV light cannot even penetrate the outer layer of dead cells of human skin or the outer tear layer of the eye surface due to its strong absorption in biological materials.

Care222 uses an excimer lamp (a mercury-free UV excimer light source produced by Ushio especially for outputting monochromatic ultraviolet with a primary wavelength of 222 nm) in combination with a special optical bandpass filter (200 to 230 nm) which passes only ultraviolet wavelengths that have no harmful effect on people.

The use of Care222 in public places is a safe and effective way to limit the spread and transmission of air-mediated microbial diseases, such as schools, hospitals, stadiums, sports grounds and offices, and this approach may help to limit seasonal infections, the spread of tuberculosis and major epidemics. It’s inevitable far uvc will become part of the new World people are more aware and want to be protected from viruses.

Continuously disinfecting in occupied space but not harmful to skin and eyes of people, which could be used in dental offices, medical rooms, high-end offices, elevators, hospitals, class rooms, etc.
