摘要
葡萄糖是生物体和食品中普遍含有的一种重要物质,其浓度的高低直接影响着生物体功能的正常发挥和食品的质量,因此检测葡萄糖的浓度有重要的意义和作用.本文利用微型表面等离子共振生物传感器构造了葡萄糖测量实验系统,并通过葡萄糖溶液浓度的测量实验对系统的性能进行了评估,对实验现象进行了分析,探讨了测量结果的数据处理方法.实验系统对葡萄糖溶液的分辨率达到了6.25mg/L,其精度高于其他采用折射率测量方法能够获得的葡萄糖溶液浓度的测量值.实验结果表明微型化的表面等离子共振测量装置在工业和医疗上的检测有很好的应用前景.
Glucose is one of the most important components that contain in the body of organism and the food, the concentration of the glucose not only plays a significant role in exerting the normal function of organism but also in controlling the quality of food, thus to detect the concentration of glucose has important meaning. An experiment system is set up basing on a miniature surface plasmon biological senor to measure the concentration of glucose solution. The phenomenon of the experiment and the method for the data processing are analyzed, the lowest detection limit of this system reaches 6.25 mg/L, which is higher than other ways of refractive index measurement, the result shows a brilliant future for the application of SPR in industry and medical treatment.
