Abstract
The synthesis of plasmonic nanorattles with accessible electromagnetic hotspots that facilitate highly sensitive detection of chemical analytes using surface enhanced Raman scattering (SERS) is demonstrated. Raman spectra obtained from individual nanorattles demonstrate the significantly higher SERS activity compared to solid plasmonic nanostructures.
摘要
展示了具有可及电磁热点的等离子纳米瓶的合成，这些热点有利于使用表面增强拉曼散射（SERS）对化学分析物进行高灵敏度检测。与固态等离子体纳米结构相比，从单个纳米瓶获得的拉曼光谱表明其具有更高的 SERS 活性。
