摘要
Glucose biosensor based on screen-printed electrodes and glucose oxidase (GO(x)) layer modified by aminated multi-walled carbon nanotubes (MWCNT-NH2) has been developed. The optimal membrane composition for enzyme immobilization by covalent binding in saturated GA vapors was determined as 0.1% of GO(x), 0.25% of MWCNT-NH2, 6.0% of bovine serum albumin (BSA), and 5.0% of glycerol. It has been shown that the integration of MWCNT-NH2 into GO(x) membrane is an effective approach to extend the linear dynamic range of glucose determination and to improve the biosensor sensitivity. However, analytical performances of the MWCNT-NH2 modified biosensor are restricted in terms of lowering its detection limit.
