✦ Synopsis
A new small-volume electrochemical cell for the entrapment of biological recognition elements in electrochemically deposited conducting polymer films has been developed. It allows one to save significant amounts of the monomer and especially of the used biological recognition element, and hence permits one to choose very expensive enzymes for the development of respected biosensors. Since the conductivity, morphology and film thickness of the obtained conducting polymer films are dependent on the presence of molecular oxygen, the electrochemical cell allows a facilitated handling of the electrode and electrolyte solution under strict exclusion of any oxygen. To prove the applicability of the new electrochemical cell, the entrapment of glucose oxidase into polypyrrole films has been performed as an example.
