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.
Metal nanoparticles are of great significance for the study of surface plasmon resonance, and the functional assembly formed by self-assembly can exhibit more excellent overall synergistic performance.In this paper, the gold nanorods are directly assembled by femtosecond laser processing without introducing other , The process is simple and fast (about 1 min), which not only retains the surface plasmon properties of the gold nanorods, but also can achieve any fine patterning of the gold nanorods.The assembly of the micro / nanostructures for microfluidic chip surface enhancement Raman scattering detection, can be very good enhancement, providing a new method for the preparation of plasma devices.
