BIOMOLEC · Functionalized biopolymers for application in molecular electronics and in photonics

The project will unite efforts of leading laboratories of 5 countries: France, Romania, Poland, Brazil and Russia to render the two well known biopolymers: DNA and collagen applicable in molecular electronics and in Photonics Marine DNA, extracted from waste in salmon industry and commercial collagen will be used to obtain biodegradable photoresponsive materials for application in photonics and in molecular electronics.Biodegradable and coming from renewlable ressources pure DNA and collagen, well known biopolymers, are chacterized by an ionic electrical conductivity and photoinactive large transparency range material. These materials will be functionalized with photoactive chromophores such as 1D charge transfer molecules to render them photoresponsive. On the other hand doping with such molecules as PEDOT, fullerenes and particularly the nanotubes will increase significantly the charge mobility and make the biopolymers applicable in optical signal processing, molecular electronics and solar energy conversion. At the output of the project materials with controllable charge mobility and nonlinar optical response will be obtained. Practical applications, particularly in solar energy conversion and in making smart windows will be demonstrated
