Abstract

Photochemical and thermal stability of thin films formed from selected optically responsive chromophores embedded in deoxyribonucleic acid (DNA), Collagen and in the complex formed by DNA biopolymer and the surfactant hexadecyl ammonium (CTMA) matrix was studied by UV-VIS and compared with that observed when using some synthetic polymers (polymethylmetacrylate – PMMA, polycarbonate – PC). In particular the influence of external stimuli, such as heating and UV light on the chemical degradation process was investigated.
