Abstract

A method is provided for electrochemically depositing a polymer with spatial selectivity. A substrate having a substrate surface is contacted with an aqueous solution containing a selectively insolubilizable polysaccharide, such as chitosan, which is subjected to electrochemically treatment to deposit, with spatial selectivity, the selectively insolubilizable polysaccharide on a patterned electrically conductive portion of the substrate surface.
