Abstract
In Phase I, Rainbow Communications demonstrated the proof of the principle of innovative gallium nitride (GaN) based light-emitting diodes (LED) for pathogen elimination, wound healing, and tissue regeneration. In Phase II, Rainbow will improve the designand fabrication of the GaN based LED devices, adding the following new features: (1) new architecture of GaN based LED source; (2) new LED and device packaging technologies; (3) new thermal management system for the high power and high performance LED; (4)rugged packaging that utilizes Rainbow¿¿s unique glue technologies for very rough environmental conditions; (5) integrating the GaN LED with optical coherent tomograhpy (OCT) and optical Doppler tomography (ODT) systems for wound healing studies based onchick chorioallantoic membrane (CAM), an organotypic (RAFT), and rodent burn models; (6) clinical studies of wound healing using the developed GaN LED based on human models. The proposed GaN LED devices will find many applications for warfighters.
