Abstract:

Abstract Three dimensional nanoporous gold, with an average ligament size of 50 nm, was fabricated by chemical de-alloying from a new Au based metallic glass precursor. The resultant nanoporous gold gives rise to superior surface enhanced Raman scattering (SERS) capability using 4,4′-bi-pyridine as probe molecules. The SERS intensity ma...More
