In this letter, the glucose biosensor was based on glucose oxidase (GOx) to catalyze the oxidation of glucose. The weak immobilization strength of GOx would lead to the poor sensing characteristics. In order to enhance immobilization strength of GOx, the magnetic beads (MBs) combined with GOx to form the Nafion-MBs-GOx /indium gallium zinc oxide (IGZO) glucose biosensor. Besides, the glucose biosensor modified by different contents of MBs solution was investigated to obtain optimal content of MBs. The Nafion-MBs-GOx /IGZO glucose biosensor with 1.00 ml MBs solution had the optimal average sensitivity and linearity which were 7.390 mV/mM and 0.994, respectively. (c) 2016 Elsevier B.V.
