There is little information on micelles of naturally occurring amphiphilic polymers and their derivatives. Chitosan of (1,4) linked 2-amino-β-D-glucan is the second most abundant biomass and known as a good candidate material for biomedical uses due to its biocompatibility and biodegradability. The molecular weight of chitosan was comparatively precisely controlled by depolymerization method with nitrous acid. The mean diameter and the critical aggregation concentration of chitosan amphiphiles depended on the molecular weight of chitosan. It was observed that the molecular weight effect on the micelle formation was less influential for the molecular weight above 40 kDa.
