Fabrication of 3D SERS-active Substrate based on Ni foam with High Surface Area by Using Thermal and Plasma Treatment |
| 초록 |
SERS(Surface-enhanced Raman Spectroscopy) is a highly sensitive molecular detection technique that enhances Raman scattering of molecules adsorbed on roughend metal surfaces or nanostructures. Nickel foam with a three-dimensional(3D) structure can provide more hot spots and a large specific surface area. We aimed to fabricate a 3DSERS-active substrate to have high sensitivity. In this study, SERS substrate was formed by gold deposition after making nanostructures with surface modification through thermal and plama ething treatment. As a result, the SERS substrate was able to detect very low concentrations of rhodamine 6g with excellent stability and reproducibility. |
