Using this method, an enhancement factor of 109 is achieved for the probe molecule of rhodamine 6G (around two orders of magnitude higher than previous results based on Ag-coated BS) in surface-enhanced Raman scattering (SERS) measurement.

Using this method, an enhancement factor of 109 is achieved for the probe molecule of rhodamine 6G (around two orders of magnitude higher than previous results based on Ag-coated BS) in surface-enhanced Raman scattering (SERS) measurement.
