摘要

设计了具有克雷奇曼棱镜耦合结构的金纳米天线阵列作为高灵敏度生物传感器。为了获得更高的近场增强，利用全内反射(TIR)将输入能量转移到局部表面等离子体共振(LSPR)中。基于这种几何结构，观察到多种耦合模式，电场强度比传统金膜传感器高6.9倍。

SPR biosensor using gold nanoantenna arrays in Kretchmann configuration

Gold nanoantenna arrays with Kretchmann prism coupling configuration are designed as high sensitivity bio-sensor. In order to achieve higher near-field enhancement, total internal reflection (TIR) is used to transfer the input energy into localized surface plasmon resonance (LSPR). Base on this geometry, multiple coupling modes are observed and the magnitude of electric field shows 6.9 time higher than the traditional gold film sensor.
