Tunable morphology of lipid/chitosan particle assemblies.

Lipid/chitosan (CS) particle assemblies have recently been developed as new promising carriers for drug delivery applications. The present work reports for the first time the formation of such assemblies by a simple spontaneous adsorption of lipid membranes onto the CS particle surfaces. As shown by dynamic light scattering (DLS) measurements, final non-aggregated assemblies with relatively satisfactory size distributions were obtained by using this process.
