Abstract

We present the fabrication and performance of an ultra-sensitive, high-absorbing, yet simple-to-fabricate plasmonic nanocavity antenna structure fabricated inside fluidic channels. The novel fabrication is based on nanoimprint lithography and multiple resist layer etching. And large fluorescence enhancement (~20X) of DNA molecules (YOYO-1 dye labeled) on the plasmonic antenna was observed, demonstrating its potential in fast and real-time biochemical sensing applications.
