Abstract

The electrochemically triggered dissolution of noncontinuous polyelectrolyte assemblies presenting distinct nanomorphologies and its tuning by chemical cross-linking were monitored locally, in situ, by electrochemical atomic force microscopy. Poly-l-lysine and hyaluronic acid deposited layer-by-layer on indium tin oxide electrodes at specific experimental conditions formed well-defined nanostructures whose morphologies could be easily and precisely followed along the dissolution process. In addition to shrinkage of polyelectrolyte nan
