NEW WAY TO TREAT SKIN CONDITIONS:
WORLD’S FIRST MERCURY-FREE FILMTYPE ULTRAVIOLET LIGHT SOURCE
The Kobe University Graduate School of Engineering and the Graduate School of Medicine have jointly developed the world's first new mercury-free light source that produces ultraviolet radiation for medical applications.
The technology for the "made-to-order skin treatment equipment" is possible due to an industry-academia-government collaboration. It is currently being certified as a medical instrument, and sales are expected to begin in October 2015. This equipment should effectively treat skin diseases such as atopic dermatitis, leucoderma, and psoriasis. Because it can deliver high-intensity radiation to only the affected area, it should reduce the treatment time and patients' stress.
Unlike conventional electron-beam excitation methods for phosphor excitation, the plasma excitation method employs technology similar to that used in plasma televisions, allowing a large area to be treated. However, its biggest advantage is its ability to pinpoint the location where light is delivered. Hence, it can precisely deliver UVB radiation to only the affected area.
Professor Kita Takashi of Kobe University says, "The results of this study are revolutionary, and may reshuffle the power relationships for medical ultraviolet light sources. We have already successfully developed a light source with a bactericidal wavelength of 263 nm. In the future, we hope to further improve this technology and realize applications for water sterilization and other uses."
