Plasmofluidic Nanoporous Gold Membranes for Ultrasensitive Raman Spectroscopy

Not Accessible

Your library or personal account may give you access

Abstract

A label-free and ultrasensitive surface-enhanced Raman spectroscopy technique based on suspended plasmonic nanoporous structures is demonstrated. Drastically enhanced local fields and optofluidic analyte delivery is used to enhance detection limits.
