Size-controlled polyelectrolyte complexes: direct measurement of the balance of forces involved in the triggered collapse of layer-by-layer assembled nanocapsules.


Polyelectrolyte multilayers composed of poly(allylamine hydrochloride) and poly(styrene sulfonate) were assembled on 13 nm gold nanoparticles and characterized by Transmission Electron Microscopy and Atomic Force Microscopy. The direct measurement of the interactions at the molecular level using a Surface Force Apparatus revealed that the colloidal… (More)
