Hollow Au/Ag Nanoshell Embedded Silica Nanospheres as SERS probes for Bio-applications |
초록 |
Metal nanoshells are of great interest in various fields as catalysis, drug delivery vehicles, optical imaging and photothermal therapy agents. In particular, hollow Au/Ag nanostructures have tunable extinction band from visible to NIR region (ca. 400-1200 nm). In this study, we report the preparation of hollow gold/silver nanoshell embedded silica spheres (GNES) as NIR sensitive SERS nanoprobes. The Au/Ag nanoshells were formed on the surface of silica sphere from Ag NPs on silica sphere via galvanic replacement reaction. |
