Fe3O4@Au Core-shell Nanoparticle with Suprastructure Au shell for SERS |
| 초록 |
In this study we specially synthesized suprastructure like core-shell nanoparticle under the wet chemistry environment. Assembled structrue of Au nanoparticles were fully covered Fe3O4 nanoparticles and observed by TEM. Au shell can protects the magnetic core against oxidation and produces multifunctionality, special optical properties from suprastructure like Au shell and magnetic properties from magnetic nanoparticles. To form suprastructure like Au NP coating on Fe3O4 nanoparticles, ion reducing method assisted with layer-by-layer (LBL) structure of AuNPs and PEI on the surface of Fe3O4 nanoparticle were proceeded. This material was used as surface enhanced Raman scattering (SERS) substrate of rhodamine-B and graphene quantum dots (GQDs). Magnetically 1D self-assembled structure of the prepared core-shell nanoparticles and separately deposited nanoparticles were prepared as SERS substrate. Raman signals on these two substrate were obtained and compared |
