This thesis deals with the preparation of multi-channel
electrochemical biosensor for analysis of polyphenols in
selected samples of beer. The theoretical part is focused on
the characterization of polyphenolic compounds, their
properties and determination. Further there is analyze problems
od enzyme biosensors with electrochemical converter.
In the experimental part were summarized the preparation of
bioelectronic tongue using enzymes oxidizing phenolic compounds
and prepared calibration of single- and four-channel biosensors
using automated dispensing samples. Furthermore, real beer
samples was measured by this method.
