M. Yasuzawa et al., Properties of glucose sensors prepared by the electropolymerization of pyrroles containing phosphatidylcholine (II), SENS ACTU-B, 66(1-3), 2000, pp. 25-27
New hemocompatible glucose sensors were prepared by electropolymerization o
f pyrrole derivatives having phosphatidylcholine, 5-(1-pyrrolyl)pentyl-2-(t
rimethylammonium)ethyl phosphate, in the presence of glucose oxidase (GOD),
with an inner-membrane of Nafion or poly(o-phenylenediamine) (PPD). The in
troduction of these membranes not only eliminated the influence of ascorbic
acid on the sensor response but also increased the electrode stability. Th
e electrode responses containing PPD inner-membrane were shown to be relati
vely constant for more than 200 days or three times as long as the electrod
e responses without the inner membranes. (C) 2000 Elsevier Science S.A. All
