Limited number of electrochemical experiments with the purpose of sensitive quantification (<
nmol dm-3) of polysaccharides has been performed up to now by using voltammetric and/or
chronopotentiometric methods. Polysaccharide-protein interactions are expected to be one of
the most significant interactions in the real medium, like for example in seawater or in biological
materials. From the analytical point of view, those interactions are one of the crucial factors
which would interfere qualitative and quantitative sensing of polysaccharides in the mixture.
Elucidation of the type of their interactions by interdisciplinary assay will serve as a base for
electrochemical sensing of polysaccharides in buffer solution and in seawater, without or with
usage of appropriate separation technique. Thus, mentioned electrochemical methods have not
been employed in the investigation of such interactions.
