Conductometric enzyme biosensors: theory, technology, application

S. V. Dzyadevych

A theoretic principles of conductometric method of mesurements, possibility of their application for registration of enzymatic reactions, and examples of such application have been shown. Variants of different conductometric transducers for biosensor creation, immobilisation methods of active material onto surface, measurements schemes and methods have been presented. Some examples of conductometric enzyme biosensors, their advantages and disadvantages, and perspectives of their application have been described.

Key words: conductometric biosensor, impedance, condcutance, enzyme.
