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.
