Stability of GOX immobilized in an LBL assembled nylon membrane, as well as in a PVDF–PAA–PAH membrane based on the change in activity over a period of time. The stability is compared with that reported for free GOX.13 Activity is calculated based on concentration of H2O2 and is normalized by dividing by the activity on the first day of immobilization at pH 5.5.
