UNLABELLED
Inkjet printing technique is exploited for the synthesis of Ag nanoparticles (NPs) patterned on electrochemically etched silicon-based substrates. The nanostructure morphology, here analyzed by scanning electron microscopy, is dictated by the ink composition and the printing parameters. Under suitable excitation conditions, resonant surface-enhanced Raman scattering (SERS) performed on such metal-dielectric nanostructures can approach single-molecule detection as recently demonstrated on silvered porous silicon synthesized by immersion plating.

喷墨打印技术被用于在电化学蚀刻的硅基衬底上图案化 Ag 纳米粒子 (NPs) 的合成。扫描电子显微镜分析表明，纳米结构形态取决于墨水成分和打印参数。在合适的激发条件下，对这种金属-介电纳米结构进行共振表面增强拉曼散射 (SERS) 分析，如最近在通过浸镀合成的镀银多孔硅上所证明的那样，可以达到单分子检测的水平。
