摘要

在这项研究中，我们提出了一个使用高可调纳米球光刻(NSL)技术的小型化遥感SERS平台的简单制造。采用直径200 μm的高数值孔径光纤(0.5NA)，遥感的SERS增强是直接遥感配置的98%。标准二氧化硅光纤用于使用SERS进行遥感，而不需要额外的光学滤波来减轻这些光纤的荧光和拉曼背景，从而允许制造可用于远程生化传感的小型化遥感平台。

Miniature optical fiber sensors using surface enhanced Raman spectroscopy (SERS) for remote biochemical sensing

In this study, we present facile fabrication of a miniaturized remote sensing SERS platform using highly tunable Nano-Sphere Lithography (NSL) technique. Using 200 μm diameter optical fibers with high numerical aperture (0.5NA), the SERS enhancement of remote sensing was found to be 98% of direct sensing configuration. Standard silica optical fibers were used for remote sensing using SERS without additional need of optical filtering to mitigate fluorescence and Raman background of these fibers which allows fabrication of miniaturized remote sensing platforms that can be used for remote biochemical sensing.
