Assembly of Plasmonic and Magnetic Nanoparticles for Dual-function Light Scattering-Magnetic Probe |
| 초록 |
The silica coated superparamagnetic Fe3O4 nanoparticles (MNPs) have unique properties that can be controlled by external magnetic field. Also, gold nanoparticles (Au NPs) have various peoperties which of generation of surface plasmons that absorb light and enhance an electromagnetic field by the collective and resonant excitation of free electronsand. The hybrid nanoparticles using these two NPs are can be made more effectively by utilizing the advantages of materials. In this study, we report fabrication of multifunctional material containing MNPs and clustered Au NPs. First, the monodispersed silica coated magnetic nanoparticles (MNP@SiO2 NPs, 104.2 nm ± 2.4 nm) that synthesized of gram-scale synthetic showed superparamagnetism and no aggregation was detected. Also, Fe3O4@SiO2@Au NPs that synthesized by additional modifications were also prepared by simply adding Au NP to magnetic NPs and showed 500 % higher light scattering than single gold NPs of the same size. |
