论文摘要
最近，研究了可以基于局部表面等离子体（LSP）或表面等离子体偏振子（SPP）结构的尝试结合表面增强表面增强表面增强的拉曼光谱法（SERS）底物的研究。通过组合这两个系统，可以互相解决。但是，到目前为止所涉及的制造方法是精致，劳动密集型，昂贵且技术要求的。我们提出了一种用于制造柔性等离子纳米斜率SERS传感器的简便方法。我们在周期性的光盘（DVD-R）上利用了该模式作为廉价的替代品，用于用软性印刷印刷术在PDM上打印周期性模式。使用动态倾斜角度（DOD）技术通过串行双重定位来制造Ag纳米斜率（AGNS）。纳米斜体结构在物理上和光学表征上进行了表征，并将实验结果与数值模拟研究进行了比较。蒙特卡洛和有限差分时间域（FDTD）模拟。 Ag纳米斜率结构显示出极好的SERS增强功能，其生物传感能力是通过感应胆红素的。
Recently, studies have been carried out on attempts to combine surface-enhanced Surface-enhanced Raman spectroscopy (SERS) substrates that can be based on either localized surface plasmon (LSP) or surface plasmon polaritons (SPP) structures. By combining these two systems, the drawbacks of each other can be solved. However, the manufacturing methods involved so far are sophisticated, labor-intensive, expensive, and also technically demanding. We propose a facile method for the fabrication of a flexible plasmonic nanoslit SERS sensor. We utilized the pattern on periodic optical disks (DVD-R) as a cheap substitute for printing the periodic pattern on PDMS with soft imprint lithography. Ag nanoslit (AgNS) was fabricated by serial bideposition using a dynamic oblique angle deposition (DOD) technique. The nanoslit structures were physically and optically characterized, and the experimental results were compared to the numerical simulation studies; Monte Carlo and the finite-difference time-domain (FDTD) simulation. The Ag nanoslit structure showed an excellent SERS enhancement, and its biosensing capability was demonstrated by the sensing of bilirubin.
