Abstract
A nanoporous gold disk (NPGD) as a novel surface-enhanced Raman spectroscopy (SERS) substrate. NPGD has SERS enhancement factor similar to that of gold nanoshells, but allows, for example, at least three times more benzenethiol molecules to be attached to its surface due to large surface-to-volume ratio. The high capacity enables the rapid detection of attomole-level benzenethiol molecules with relatively high detector temperatures. Additionally, a fabrication process to make NPGD with controlled size and highly reproducible SERS activities.
