Abstract
The system in which reaction-diffusion (RD) transforms microscopic patterns of chemicals delivered onto thin films of dry gelatin into regular arrays of lines was analyzed. It was observed that the color-patterned gels were used as high-quality diffraction gratings and photolithographic masks. It was observed that the colored portions of the films prepared with concentrated (1 M) FeCl3 were opaque to UV radiation and the photoresist had binary topography. The color-patterned gels were also used in the fabrication of arrays of planar wave-guides and in sensory/assay applications.
