Title:
スーパーオキシドアニオン用電極およびこれを用いるセンサー
Document Type and Number:
Japanese Patent JP4382088
Kind Code:
B2
Abstract:
An electrode for superoxide anions characterized by comprising a conductive component and, superimposed on a surface thereof, a film resulting from electrolytic polymerization of a metal thiofurylporphyrin/axial ligand complex; and a sensor for measuring a superoxide anion concentration including the same. The electrode for superoxide anions, by virtue of not only the excellent performance of electrode provided with the metal porphyrin complex polymer film, but also the presence of the axial ligand, can prevent poisoning by a catalyst poison such as hydrogen peroxide. Accordingly, in any of in vitro or in vivo environments, this electrode for superoxide anions enables detection of superoxide anion radicals without suffering any influence from a catalyst poison such as hydrogen peroxide. Moreover, quantitative assay of superoxide anions can be performed by the use of this electrode for superoxide anion in combination with a counter electrode or a reference electrode. Thus, this electrode for superoxide anions can find wide applicability in various fields.
