Metallic nanostructures for biomedical application require plasmonic protperty in NIR region and biocompatibility. for that, noble metallic nanoparticles with reduced- symmetry such as gold nanorod have been widely investigatd. Especially, symmetry-broken nanoparticle with sharp edges is a good candidate since it could improve the plasmonic property. Herein we propose a facile synthesis of crescent-like gold/silica nanoparticle by using 100nm gold /silica dimer as a seed. By taking advantages of biocompatibility and room temperature synthesis, we use silica part as a physical barrier. We expect our particle can be used in a wide range of biophonic applications for optical nanoplasmonics such as targeting, sensing/imaging, gene delivery, and optical gene regulations. |
