Scientists from Columbia University’s Center for Radiological Research have shown that a narrow wavelength of ultraviolet light safely killed drug-resistant MRSA bacteria in mice, suggesting its potential to reduce surgical site infections. 

 

A paper just published by PLOS ONE describes how the Columbia team found that a particular wavelength of UV light known as “far-UVC” (in this instance, 207 nanometers) is not only as effective as conventional germicidal UV light in killing MRSA, as shown in their previously published study, but also shows for the first time that, unlike conventional germicidal UV, far-UVC does not cause biological damage to exposed skin.
