Researchers at the Ferdinand-Braun-Institut (FBH) in Berlin have successfully produced the first prototypes of micro-LEDs that emit in the ultraviolet spectral range (UVB). The micro-LEDs with 310 nanometers (nm) emission wavelength feature a small size of the emitting area with diameters down to 1.5 micrometers (µm). This is hundreds to thousands of times smaller than conventional UV LEDs. The micro-LEDs can be closely packed with pitches down to 2 µm to form a two-dimensional array on a chip, resulting in high-resolution UVB emitting areas.

Hiroshima University and Ushio Inc. have been conducting a joint research project (Study on the disinfection (*1) and viral inactivation effects of 222 nm UV-C light using Care222). As part of this study, a group of researchers, including Professor Hiroki Ohge of the Department of Infectious Diseases at Hiroshima University Hospital, and Professor Takemasa Sakaguchi of the Virology Section of the Graduate School of Biomedical and Health Sciences at Hiroshima University, evaluated the effect of irradiating a SARS-CoV-2 variant (*2) with Ushio's Care222 filtered Far UV-C light disinfection technology. The research showed that Care222 technology is equally effective in inactivating a SARS-CoV-2 variant as in inactivating the original SARS-CoV-2 strain.
