Layer-by-Layer Self-Assembly of Polyelectrolyte and Low Molecular Weight Species into Capsules

Composite capsules containing low molecular weight species together with charged macromolecules have been prepared both in aqueous and organic solutions. Dyes were used as building blocks to quantify the adsorption. The Figure shows a tapping mode scanning force microscopy image of capsules consisting of poly(styrene sulfonate) and benzoquinone layers templated on melamine formaldehyde particles (see also inside front cover).
