Self Assembled Nano-Photonic Devices Derived from Marine DNA for Opto-Electronic Applications

Abstract

Optical and photochromic properties of spiropyran-intercalated DNA-surfactant complex films were studied for optical switching. The switching speed was observed as 200-300 ms. They depended on the type of spiropyran as well as the type of surfactant. Spiropyrans containing the oxazine ring and intercalated into DNA showed a very rapid photochromic response. It also showed that photochromic response times became much faster when intensity of the excitation light increased. Various DNA-cationic lipid complexes and their bulk films were also prepared and their physical properties were measured.
