Abstract
This paper reports the fabrication of a novel self-wetting microfluidic channel which itself is a three-dimensional localized surface plasmon resonance (LSPR) substrate. Two key improvements that are addressed are the controlled fabrication of a 3D metal nanoparticle LSPR substrate and the hydrophilic nature. Metal nanoparticles are stacked three dimensionally by a single e-beam evaporation step on periodically hinged, tapered pillar nanostructures we call "nanoscrew". Ease of fabrication and hydrophilic property of the sensing platform would make this approach suitable for plasmon-based optical sensing. The application is focused on fluorescence enhancement with opening possibilities for surface enhanced Raman scattering (SERS).
