UV sterilisation device being tested for use on human skin

An LED irradiation system has been developed at the Ferdinand-Braun-Institut in Berlin that aims to kill microorganisms with ultra-short wave UV light. The researchers anticipate that the UV light emitted from their device will not be harmful to human skin
