This paper describes a new type of plasmonic sensor fabricated by imprint lithography using a soft, elastomeric mold. Angle-dependent, zero-order transmission experiments demonstrate the sensing potential of this device, which uses a two dimensional plasmonic crystal. Full angle-dependent mapping shows that the sensitivity to surface chemical binding events reaches maxima near regions of the plasmonic Brillouin zone where the dispersion curves of multiple surface plasmon polariton modes converge. This behavior, together with the simple, low cost procedures for building the structures, suggests a potentially important role for these devices in high performance chemical and biological sensing.
本文描述了一种通过使用柔软的弹性体模具进行压印光刻制造的新型等离子体传感器。角度相关的零阶透射实验证明了该器件的传感潜力，该器件使用二维等离子体晶体。全角度相关映射表明，对表面化学结合事件的灵敏度在等离子体布里渊区的区域附近达到最大值，在该区域多个表面等离子体激元模式的色散曲线汇聚。这种行为，连同构建结构的简单、低成本程序，表明这些器件在高性能化学和生物传感中可能发挥重要作用。
