| 제목 | Synthesis of Gold nanostar for Localized Surface Plasmon Resonance (LSPR), Surface Enhanced Raman Spectroscopy (SERS) application |
| 초록 | Metal nanoparticles have different optical properties, depending on the shapes and sizes, which allowed them to be most useful in bioimaging, imaging, etc. In particular, star-shaped gold nanoparticles (gold nanostar) have the strong plasmonic extinction in near IR region andrough and sharp morphology called as 'hot spot' which can afford to generate dramatic surface enhanced Raman scattering (SERS). Here, we report the gold nanostars(AuNSs) with polyvinyl pyrrolidone (PVP) surface for molecular diagnostics. AuNSs were synthesized by PVP method efficiently, and the functionalities corresponding to a application were invested to the surface and the inside of AuNSs. The shapes and physical properties of nanoparticles at each step were characterized by TEM, SEM, ELS, etc. Finally, the feasibility as novel nanoprobes for LSPR biosensor and SERS were evaluated. |
