DNA nanotemplates as an innovative material for optic application

摘要

Messages encoded from DNA sequence provide extensional structural and functional information in constructing DNA nanostructures. Therefore, DNA is used more than just as a genetic blueprint of life, it is also as innovative building blocks for building up various innovative nanomaterials with nano-meter resolution and micro-meter scale length. Long, and single-stranded DNA with repetitive sequence was in situ synthesized on silicon-based substrate and served as a nanotemplate to incorporate variable heteroelements, including enzymes, nanoparticles. Optical properties of gold nanoparticle chains were measured and extended applications of DNA nanotemplates in optics and nanotechnology.
