Polyelectrolyte microcapsules were prepared by the layer-by-layer assembly of hyaluronic acid (HA) and a polycationic polymer, poly(allylamine) (PAH) or poly(lysine) (PLL). The influence of the polycationic partner on the morphology, stability, permeability properties, and enzymatic degradation of microcapsules was thoroughly analyzed. It Was found that these properties could be tuned by shell cross-linking. Confocal microscopy studies of cellular uptake of the capsules showed that the polyelectrolyte shells remain stable outside the cells but readily break open once internalized by cells, suggesting their potential as carrier for intracellular drug delivery.
