Synthesis of Highly Sensitive Magnetic Nanoparticles-embedded Silver Nanoshell for Label-free SERS Detection |
| 초록 |
SERS (Surface-enhanced Raman scattering) is an efficient imaging tool for multiplexed analysis of various targets because it has unique signal patterns with narrow band width and stable against photobleaching. The structure of metal substrate is very important in order to obtain strong SERS signals. So far, various approaches have been attempted to develop new type of metal substrate for sensitive detection of targets in low concentration. Here, we have synthesized a new type of SERS nanoprobe which has magnetic nanoparticles at core part, and silver nanoshell at outer part. The morphology of silver nanoshell is bumpy, which could create ‘hot spots’, leading to strong SERS signals. In addition, the SERS signal could be further increased by magnetic-induced aggregation. The nanoprobe could provide high sensitivity for the detection of various targets in low concentration. |
