Therapeutic application of light emitting diode: Photo-oncomic approach

Publication date: Available online 9 January 2019Source: Journal of Photochemistry and Photobiology B: BiologyAuthor(s): Phil-Sun Oh, Hwan-Jeong JeongAbstractAs a new light source, light emitting diode (LED) with high brightness and lower cost has been rapidly developed in medical application and light therapy. LED phototherapy can activate target cells with appropriate power and adequate energy density. This review provides general information on therapeutic applications of blue, green, yellow, red, and infrared LED in medical treatments for various physical abnormalities and on bio-imaging. The bio-imaging system is improved by decreasing the number of microscopes apparatuses including neutral-density filter, excitation filters and mechanical shutters. The numbers of excitation photons a...
