  • Title: Surface-enhanced Raman spectroscopy with monolithic nanoporous gold disk substrates.
    Author: Qi J, Motwani P, Gheewala M, Brennan C, Wolfe JC, Shih WC.
    Journal: Nanoscale; 2013 May 21; 5(10):4105-9. PubMed ID: 23334234.
    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 10(8) has been obtained on individual disks using benzenethiol self-assembled monolayer with 785 nm laser excitation.
