Biopolymer Thin Films for Photonics Applications

In this paper we focused our studies on functionalization of DNA and of collagen with active molecules and thin film processing, their photostability in view of their further application in electronics and photonics as all optical switching elements, bioleds, optical memories, light amplifies, electro-optic modulators, etc. We have also addressed very important point for the practical application of these materials, not studied previously, which is the photo stability of these materials. If they have to work in photonic systems they have to exhibit an excellent stability in time and at the operation temperature range. The main interest for biopolymers arises from the fact that they are renewable, derived from waste of meat industry and they are biodegradable materials.
