Study on fiber optic biosensors based on refractive index modulation
Author(s): 
Pages: 1006-1009
Year: Issue:  9
Journal: Laser & Infrared

Keyword:  光纤生物传感器折射率灵敏度;
Abstract: 根据光纤内光强损耗与芯外的环境有效折射率之间的关系,设计了一种结构简单、易于操作、成本低廉、灵敏度较高的折射率调制型的光纤生物传感器.文中对该传感器的结构进行了理论分析,通过对不同浓度葡萄糖溶液的检测,研究了该传感器的传感特性.结果表明:该传感器的检测灵敏度可以达到μmol/L量级,并具有较好的线性特性.
