Nano-plasmonics Sensing and Integration with Microfluidics for a Lab-on-chip Biosensor

摘要

Ordered arrays of nanostructures in metal films have been studied for practical miniaturization of surface plasmon resonance (SPR) sensing and microfluidic integration. We report a nanoslit array that is designed to permit Extraordinary Optical Transmission (EOT) with a tunable primary peak in the visible to NIR range, with the spectral shape and light transmission determined by the SP manipulation in the embedded metal film. The array structure readily interfaces with microfluidic channels, making it amenable to a lab-on-chip device.
