摘要
New hemocompatible glucose sensors were prepared by electropolymerization of pyrrole derivatives having phosphatidylcholine, 5-(1-pyrrolyl)pentyl-2-(trimethylammonium)ethyl phosphate, in the presence of glucose oxidase (GOD), with an inner-membrane of Nafion or poly(o-phenylenediamine) (PPD). The introduction of these membranes not only eliminated the influence of ascorbic acid on the sensor response but also increased the electrode stability. The electrode responses containing PPD inner-membrane were shown to be relatively constant for more than 200 days or three times as long as the electrode responses without the inner membranes.
