Enzyme biosensors have been widely exploited in clinical and food analysis, where analytes represent natural substrates
of used enzymes. At difference, in environmental analysis, pollutants (e.g. pesticides, heavy metals, etc.) are generally
detected by using enzymatic activity inhibition caused by those toxic substances. The reduced specificity of inhibition
phenomenon makes only possible the determination of sum parameters, i.e. total concentration of the substances belonging
to a certain class. On the other hand, it is expected that
