Abstract
The present invention is directed to a system and method for photoeradication of microorganisms from a target. A light source is configured to irradiate the target with purple or blue light in a pulsed mode of irradiation at an average irradiance that preferably ranges from 0.1 mW/cmto 20 mW/cm. An electronic circuit is configured to control the light source in accordance with an irradiation schedule that includes a plurality of irradiation sessions. The light source is controlled to provide the purple or blue light at a radiant exposure that preferably ranges from 0.5 J/cmto 60 J/cmduring each of the irradiation sessions. The irradiation sessions are provided at a plurality of time intervals so as to cause photoeradication of all or a portion of the microorganisms.
