Voltammetric studies on the electrochemical behaviour of membrane-entrapped hemes.
The electrochemical behaviour of Fe(III)-protoporphyrin IX entrapped into a cellulose triacetate membrane has been investigated by cyclic voltammetry. The physical entrapment into a solid matrix does not modify the redox properties of the entrapped hemes, which also act as efficient promoters in the electrochemistry of cytochrome c. Such a system represents a promising example of a simple 'solid-state' promoter, and stimulates further investigations in order to obtain more complex systems that may be of significance for basic and applied bioelectrochemistry.
