    Polysaccharides (PSs), such as dextran, yeast mannan, starch and amylose, were modified with complexes of sixvalent osmium with nitrogen ligands [Os(VI)L] and voltammetric behavior of PS-Os(VI)L adducts was studied at mercury and carbon electrodes. Using Os(VI)temed as a modification agent and adsorptive transfer stripping (ex situ) method it was possible to determine PSs at submicromolar concentrations directly in the reaction mixture.
