Abstract :
A novel refractometric sensor based on nanofiber is presented. It is used to measure the refractive indices of glucose solutions of different concentrations. The sensor has a high sensitivity and can detect an index variation of ∼10−6. In addition, by solving Maxwell equations and numerical calculations, phase shift of nanofiber caused by index change of ambient medium is obtained. Experimental results show that the measured values are in close agreement with the theoretical values. The stability of the sensor can be applied to many fields, such as biological, chemical and pharmaceutical and process control applications.
