We suggested a plasmonic platform based on a cubic pattern of gold spheres for surface enhanced Raman spectroscopy (SERS). In the case of linear polarization along the symmetry axes, the SERS enhancement per area is identical to hexagonally patterned surfaces. The validity of this model was tested using the simulation package of COMSOL Multiphysics® Modeling Software. We found an improved sensitivity in the near infrared and visible region of the electromagnetic spectrum. This method considered tolerance towards stacking faults and suggested a plasmonic platform for ultra-sensing applications. The design can be extended towards the molecular detection if the proposed plasmonic platform is used with SERS.

设计用于提高SERS分子检测灵敏度的等离子平台

我们建议基于金球立方图案的等离激元平台进行表面增强拉曼光谱（SERS）。在沿对称轴进行线性极化的情况下，单位面积的SERS增强与六角形图案化的表面相同。使用COMSOLMultiphysics®建模软件的仿真包测试了该模型的有效性。我们发现电磁光谱的近红外和可见光区域的灵敏度有所提高。该方法考虑了对堆叠故障的容忍度，并提出了用于超传感应用的等离子体平台。如果建议的等离子体平台与SERS一起使用，则该设计可以扩展到分子检测。
