Abstract
Immobilization of glucose oxidase in electropolymerized polypyrrole film on the surface of a platinum wire electrode, provides a convenient sensor for flow-injection glucose determination. An upper limit of linear response for 100 microliters injected sample volume was estimated as 20 mM, whereas a 500 microliters injected sample volume gave an estimated detection limit of 0.5 mM. A simple electrode preparation procedure allows quick electrode renewal before each series of measurements.
