This study describes enzyme electrochemistry mediated by redox active polymer using polyallylamine modified with carboxyferrocene and thioctic acid (TA). A gold electrode surface was modified with self-assembled monolayer (SAM) of this polymer. A redox active polymer modified gold electrode showed a stable electrochemical response. Glucose oxidase (GOx) was co-immobilized with redox active polymer by SAM and polyion complex formation. Cyclic voltammetry of the enzyme electrode showed the current dependency on glucose concentration.
