In this work we show an optical fiber evanescent wave absorption probe for glucose detection in different physiological media. High selectivity is achieved by functionalizing the surface of an only-core poly(methyl methacrylate) (PMMA) polymer optical fiber with phenilboronic groups, and enhanced sensitivity by using a U-shaped geometry. Employing a supercontinuum light source and a high-resolution spectrometer, absorption measurements are performed in the broadband visible light spectrum. Experimental results suggest the feasibility of such a fiber probe as a low-cost and selective glucose detector.
在这项工作中，我们展示了一种用于不同生理介质中葡萄糖检测的光纤倏逝波吸收探头。通过用苯硼酸基团对仅芯聚甲基丙烯酸甲酯（PMMA）聚合物光纤的表面进行功能化，实现了高选择性，并且通过使用 U 形几何形状提高了灵敏度。采用超连续光源和高分辨率光谱仪，在宽带可见光光谱范围内进行吸收测量。实验结果表明，这种光纤探头作为一种低成本、选择性的葡萄糖探测器具有可行性。
