Gold nanosponges (AuNS): a versatile nanostructure for surface-enhanced Raman spectroscopic detection of small molecules and biomolecules.
Prepared by simple pour and mix chemistry, gold nanosponges (AuNS) are versatile structures for surface-enhanced Raman spectroscopy (SERS). An investigation into the enhancement is performed by relating the nanostructure's morphology to the SERS signal. The potential of the AuNS in SERS-based molecular and biomolecular detection is introduced.
