Abstract

We present a simple and accurate method to improve both accuracy and precision for localized surface plasmon resonance biosensors based on gold nanotube structures. The finite difference time domain (FDTD) method and the nanoimprint lithography technique were used in simulating and fabricating the nanotubes, respectively. The method provides a direct measure for the refractive index and achieves an increased accuracy as compared to other established methods.
基于投影法的精确LSPR生物传感器:折射率的直接测量
我们提出了一种简单、准确的方法来提高基于金纳米管结构的局部表面等离子体共振生物传感器的准确度和精密度。采用时域有限差分法(FDTD)和纳米压印技术分别模拟和制备了纳米管。该方法提供了折射率的直接测量,并且与其他已建立的方法相比,实现了更高的精度。
