ABSTRACT

The paper has been devoted to a review of problems associated with designing voltammetric biosensors dedicated for the food processing industry. Such biosensors are based on techniques of the cyclic voltammetry and amperometry. Voltammetric biosensors can be obtained by the immobilisation of the biological agents (e.g. enzyms) specific for a given substance on the working electrode of the traditional measuring system of the voltammograph. Short characteristics of the voltammetric methods, the salient features of redox mediators and conducting polymers and their applications in construction of voltammetric biosensors are described. Moreover, the mechanism of action and some examples of the manufacture of voltammetric biosensors are presented. The observed development of research on voltammetric biosensors allows assuming that in future they will find application alongside conventional analytic methods in qualitative and quantitative studies of food products.

Key words: biosensor; voltammetry, enzym, redox mediator, conducting polymer, food analysis.
