title: Highly localized light field on metallic nanoarrays prepared with DNA nanofibers.
abstract: We have reported a one-step method for creating one-dimensional metallic nanoarrays on surfaces. This method is based on the processes of solvent vapor-induced buildup and controlled drying front movement, and forms parallelly aligned metallic nanoarrays exceeding several hundred micrometers in length on a poly(dimethylsiloxane) (PDMS) sheet. Strong light scattering originating from highly localized electromagnetic (light) fields was observed on prepared metallic nanoarrays. Furthermore, the enhancement of electromagnetic fields localized on prepared metallic nanoarrays strongly depended on the incident-light polarization.
