Fabrication of transparent SERS devices for pesticide detection

In this work, nanowires with high transparency are presented and utilized for fabricating Surface-enhanced Raman scattering (SERS) devices. The fabrication process of the nonowires is lithography-free, micromachining-compatible and very simple, which just consists of PI spin-coating and Ar-plasma bombardment. By sputtering a thin Au layer on the surface, a… (More)
