Review Paper


UV-LEDs are used to generate ultraviolet (UV) light with high wall-plug efficiency. UV-LEDs have a unique character of generating a relatively narrow monochromatic UV wavelength band which makes them different from other conventional light sources. LEDs have lots of advantages in size, efficiency, lifetime, and low operating temperature. LEDs have been used for medical treatments but red-colored visible LEDs have been mainly used therein before the multi-color LED chip-on-board technologies become widely available. UV-LEDs now have wider range of applications in sterilization, sensing, and detection. This paper overviews currently available fabrication techniques and biomedical applications of UV-LEDs. In addition, the challenges and future developments for commercialization of UV-LEDs' bio-application are discussed.
