Abstract

Sol-gel entrapment technique is proposed for glucose oxidase immobilization in long period grating glucose sensor. The glucose oxidase is encapsulated in transparent sol-gel matrix to detect the presence of D-glucose molecules. A sensitivity of 39.8mM/nm was achieved for the fabricated glucose biosensors.
