Tuning of glucose oxidase modified alkylacrylate polymers employed in amperometric sensor systems

The efficiency of copolymers of methyl and glycidyl methacrylates as supports for the immobilisation of glucose oxidase is discussed in terms of polymer molecular weight, polymer composition and reproducibility. Copolymer molecular weight could be correlated with the inverse of the signal obtained in response to glucose, from glucose oxidase modified polymer coated electrodes. The magnitude of the response to glucose was also dependent upon the composition of the polymer.
