Abstract

Functionalization of deoxyribonucleic acid (DNA) with surfactants, photosensitive and conductivity increasing molecules as well as thin film processing is reviewed and discussed. The comparative spectroscopic studies of chemical and photothermal stability of several chromophores show a better stability in DNA-cetyltrimethylammonium (CTMA) surfactant complexes than in polycarbonate (PC) or poly(ethylene glycol) (PEG) matrices. Also the optical damage threshold in nanosecond pulsed laser illumination is higher in thin films of bio-macromolecules such as DNA, DNACTMA, collagen than in PC. The electrical conductivity of doped DNA based systems exhibits a typical ionic character and can be improved by an appropriate doping. Practical applications of DNA based complexes are reviewed and discussed.
