Abstract
Dense two-dimensional assemblies of silver nanoparticles were fabricated over vast areas (~19 cm(2)) by utilizing a simple liquid-liquid interface assembly technique. The Raman signal for p-aminothiophenol immobilized on the assemblies was drastically enhanced by plasmon coupling-induced hot spots, and the enhanced signal showed high spatial reproducibility.
摘要
通过利用简单的液-液界面组装技术，在大面积（约 19 cm(2))上制备了密集的二维银纳米粒子组装体。组装体上固定的对氨基苯硫酚的拉曼信号通过等离子体耦合诱导的热点得到了显著增强，并且增强的信号具有高空间重现性。
