Abstract
A photoinduced approach was used to synthesize a nanocomposite system comprised of DNA biopolymer and silver nanoparticles. A photoinduced switching behavior was observed while incorporating such DNA biopolymer nanocomposite as a single layer memory device and a maximum On/Off ratio of 103 can be achieved under appropriate irradiation condition. Such technique coupled with DNA-templated nanoparticle synthesis provides a facile and convenient route for photoinduced nanoparticle-conjugated DNA biopolymers for the applications of optical signal processing, optical storage, and holography.
