摘    要:金属纳米粒子对于研究表面等离子体共振具有非常重要的意义,其自组装形成的功能组装体能够展现出更加优异的整体协同性能.本文通过飞秒激光加工对金纳米棒直接进行组装,不引入其它的修饰剂,过程简单、快速(约1 min),不仅保留了金纳米棒表面等离子特性,且可以实现金纳米棒的任意精细图案化.将组装的微纳结构用于微流控芯片表面增强拉曼散射探测,可以得到很好的增强效果,为等离子体器件的制备提供了新的方法.

关 键 词:飞秒激光加工  金纳米棒组装  图案化  表面增强拉曼散射

Abstract:Metal nanoparticle is of great importance for the study of surface plasmon resonance, and its functional assembly can show more excellent overall collaborative performance. We propose an efficient assembly of gold nanoparticles (GNP) through femtosecond laser fabrication without introducing additional modifier, which can not only retains the particle’s surface plasma resonance characteristic, but also realizes the assembling pattern of arbitrary subtle shape. We apply the assembly in microfluidic chip for surface-enhanced Raman scattering detection and achieve a very good enhancement. It provides a new approach for the preparation of plasma devices.
Keywords:femtosecond laser fabrication  assembling of gold nanorod  patterns  surface-enhanced Raman scattering
