提出了一种新型的多点传感区域的二维表面等离子体共振（SPR）传感器系统。作为一项核心技术，使用多重分束光学器件可以实现多点传感。该系统能够同时测量九个传感点。在9个传感点上得到的蔗糖标准曲线在0-10%范围内呈线性关系，相关系数为0.996-0.998，相对标准偏差为0.090- 4.0%。以S/N = 3定义的检测限为1.98 × 10−6-3.91 × 10−5 RIU。这种灵敏度与传统SPR传感器的灵敏度相当。
A novel two dimensional surface plasmon resonance (SPR) sensor system with a multi-point sensing region is described. The use of multiplied beam splitting optics, as a core technology, permitted multi-point sensing to be achieved. This system was capable of simultaneously measuring nine sensing points. Calibration curves for sucrose obtained on nine sensing points were linear in the range of 0–10% with a correlation factor of 0.996–0.998 with a relative standard deviation of 0.090–4.0%. The detection limits defined as S/N = 3 were 1.98 × 10−6–3.91 × 10−5 RIU. This sensitivity is comparable to that of conventional SPR sensors.
