The present invention relates to methods and devices for diminishing microbes. The invention provides methods and devices to sanitize, disinfect and sterilize areas, spaces, surfaces and items as well as to sanitize human skin. The methods and devices will be of major importance to the healthcare industry and to other industries or physical environments that require sanitizing, disinfecting or sterilizing. The methods comprise the use of near infrared light (NIR), UV, violet and blue emitting LED elements as well as OLED (Organic Light-Emitting Diodes) as a stand-alone technology. Optionally the system may be used in combination with ozone and ionized silver.
