Surface-enhanced Raman spectroscopy with monolithic nanoporous gold disk substrates

Author affiliations

Abstract

Monolithic hierarchical nanoporous gold disks, 500 nm in diameter, 75 nm in thickness and 3.5 nm in pore radius, have been fabricated by hybrid processes. A surface-enhanced Raman scattering enhancement factor of at least 108 has been obtained on individual disks using benzenethiol self-assembled monolayer with 785 nm laser excitation.
