Abstract: Control orientation and interparticle spacing of self-assembled nanoparticles can provide versatile functional materials for optical and electronic applications. In this study, we have obtained a glass substratum with tunable optical properties using flowing control and bimolecular competition. The surface of glass was modified from immobilized stretchable gold nanoparticle chains. The long and periodic single-stranded DNA nanotemplates were prepared using Phi29 DNA polymerase molecular machinery according to precise molecular biology regulation. Gold nanoparticle (Au NP) docked at the default sites of the nanotemplates and optical anisotropic absorption were enhanced by approximately 55 % by using tunable, flexible, and oriented one-dimensional metallic nanostructures.
