摘要
表面增强拉曼光谱(Surface-enhanced Raman spectroscopy,SERS)是一种高灵敏度、高分辨率的分子识别技术,在多个领域具有非常重要的应用价值。飞秒激光直写作为一种新兴的低成本、高分辨率、高灵活性的微纳加工方法,在制备SERS基底领域得到了广泛的应用。本文重点概述了四种飞秒激光直写制备SERS基底的加工方法,主要包括飞秒激光双光子还原、飞秒激光切割金属、飞秒激光切割-溅射、飞秒激光3D打印。文章简单介绍了各方法制备SERS基底的性能与应用场景,阐述了飞秒激光直写加工在制备SERS基底中的优势,旨在为今后相关研究提供参考。
Surface-enhanced Raman spectroscopy(SERS)technique plays an important role in molecular recognition fields due to its highly sensitive and high-resolution.As an emerging low-cost,high machining accuracy,and high-flexibility processing method,femtosecond laser direct writing processing has been widely used in the field of preparing SERS substrates.This work introduces four methods of preparing SERS substrates by femtosecond laser direct writing,including femtosecond two-photon reduction,femtosecond laser cutting metal,femtosecond laser cutting-sputtering,and femtosecond laser 3D printing.The article introduces the performance and application scenarios of each method in preparing SERS substrates and illustrates the advantages of femtosecond laser direct writing processing in preparing SERS substrates,aiming to provide a reference for future related research.
