Nobel physics laureate Shuji Nakamura says ultraviolet light-emitting diodes (UV LED) will grow in importance as a next-generation LED technology that can help eradicate deadly infectious diseases worldwide.

"UV LED allows us to access clean, purified water, and this will be widely used to eliminate diseases such as Middle East Respiratory Syndrome (MERS) or Ebola," the Japanese-born American blue LED inventor said at a press conference, Thursday.

Ultraviolet refers to a light spectrum with a shorter wavelength than visible light. In particular, UVC light, one of the UV wavelength ranges, can prevent bacteria or other forms of micro-organisms from reproducing and polluting water.
