WebThe DA concentration was 300 nM, and the concentration of other substances was 1 μM. The SERS intensity of the peak at 767 cm −1 of the Ag NP dimer sensor containing 300 nM DA was ~5-fold higher than those of five substances . It needs to be emphasized that the SERS intensity showed no obvious enhancement with these interfering substances ... Webuse as a SERS substrate. The marriage of these components presents an exclusive combination of tightly focused amplification of Localised Surface Plasmon (LSP) fields inside the material with an extremely high surface-to-volume ratio. This provides favourable conditions for a single molecule or extremely low concentration detection by SERS. town station cary nc
