Abstract:
An illumination system for biological applications, wherein the system employs at least one nanostructured optical fiber. The fiber is preferably wound around a support structure to form a light-source fiber portion where guided light is scattered from the fiber outer surface to form an extended light source that emits substantially uniform radiation. The bends in the light-source fiber portion are formed to enhance the amount of scattering in the nanostructured fiber. Counter-winding the at least one fiber serves to increase the uniformity of the radiation by countering the effects of decreasing emitted radiation along the length of the light-source fiber portion. Multiple fibers wound in sequence around a support structure, with each fiber coupled to the light source, can be used to form a lengthy extended source. The light-source fiber portion can be configured to suit a variety of biological chamber geometries.

Abstract:
The invention disclosed includes a coating composition for siliceous surfaces. The coating (16) includes at least one component from the group consisting of poly(alkoxy)silane, poly(halo)silane, alkoxy silane, halo silane, and mixture thereof and a catalyst compound which generates a proton to hydrolyze the component when exposed to radiation. Preferably, the catalyst is a photo-acid. The invention also includes a method of coating the optical fiber (10). The aforementioned coating (16) is applied to an exterior surface of the fiber (14). A proton is generated to promote the hydrolysis of the component. The invention further includes a method of accelerating adhesion between the exterior surface (14) of the article and the coating (16). The inventive coating (16) is applied to the surface of the fiber (14) and the coating (16) is exposed to a radiation source.
