摘要

A high sensitive glucose sensor using microfiber based Mach-Zehnder interferometer (MZI) is proposed. Microfiber is firstly immobilized with glucose oxidase (GOD) and then employed as sensing probe in MZI. By tracking the shift of the interference spectrum, a high sensitivity up to 2.46nm. (mg/ml) ^-1 is achieved at the glucose concentration range of 0-3mg/ml.
