摘要

一种新型的，紧凑的，免疫测定生物传感器的概念，可以同时检测多种分析同时正在研究。介质平面波导传感器依靠局部倏逝场的调制耦合到阵列探测器中。使用近场扫描光学显微镜(NSOM)在17 nm厚的伪层上进行的概念验证实验显示出高灵敏度，光学信噪比约为55:1。实测结果与数值模拟结果吻合

Initial demonstration of a local, evanescent, array coupled biosensor concept

A concept for a novel, compact, immunoassay biosensor that can simultaneously sense multiple analytes simultaneously is being investigated. The dielectric planar waveguide sensor relies on modulation of the local evanescent field coupled into an array detector. Proof of concept experiments carried out using near-field scanning optical microscopy (NSOM) on a 17 nm thick pseudo-adlayer demonstrated high sensitivity with an optical SNR of approximately 55:1. The measured results agree with numerical simulations
