| Abstract: | In this study, the feasibility of introducing redox property to an amphiphilic phospholipid polymer (PMBN) was investigated.
The active ester group in the side chain of the polymer was used to react with pyrroloquinoline quinine (PQQ). Redox peaks
that corresponded to PQQ redox potentials were observed after the modification. Glucose oxidase was immobilized to the modified
polymer. Electrochemical oxidation of glucose was carried out with the polymer electrode. The oxidation current increased
with elevating glucose concentration indicating electron transfer established between the electrode and enzyme. It suggests
that by modification, PMBN is possible to use for enzyme electrode for bioelectronics. |
