Chemical modification cation-exchange process

Modification of electrode surfaces with polymer is seeking the same objective as with monolayers, i.e., the improvement of the analytical performances in terms of selectivity and sensitivity. These improved performances can be achieved by the nature of the polymer itself (e.g., perfluorinated cation-exchanger Nafion ) or by the incorporation of chemical functionalities. Recognition elements (e.g., biomolecules, ligands) can be entrapped during the polymerization process (electro- or photopolymerization) or attached after polymerization by chemical grafting or by...
