NOTA's LANOR system, developed in collaboration with the University of Michigan, uses the photochemical conversion of an NO donor molecule via UV/LEDs to produce and modulate iNO generation. Photochemical technology is simple, inexpensive, and easily controllable. LANOR employs a film cassette that is coated with a proprietary chemistry. By varying the LED light source intensity and the speed of the film moving past the light source, the system's controller is able to accurately generate NO for long periods of time. LANOR is compact and ideal for home use.
