제목 Highly Sensitive Magnetic Silica Nanoparticles-embedded Silver Nanoshell for Label-free Organic Chemical Detection
초록 SERS (Surface-enhanced Raman scattering) promises as an efficient tool for identification of diverse targets because it has stability against photobleaching and unique signal patterns with narrow band width. To obtain powerful SERS signals, the structure of metal substrate is crucial. Until now, varied approaches have been attempted to sensitively detect targets in low concentration. Herein, we have synthesized magnetic silica nanoparticles-embedded silver nanoshell that has both magnetic and SERS properties for SERS detection. The bumpy silver nanoshell could produce ‘Hot Spots’, guiding to powerful SERS signals. Furthermore, magnetic-induced aggregation made SERS signals further stronger.
