Preparation and characterization of -cyclodextrin grafted -maleoyl chitosan nanoparticles for drug delivery.

-cyclodextrin (CD) grafted N-maleoyl chitosan (CDNMCS) with two different degrees of substitution (DS) of -maleoyl (DS = 21.2% and 30.5%) were synthesized from maleic anhydride and chitosan bearing pendant cyclodextrin (CDCS).
