Apart from these properties, the release kinetics can be manipulated in such a way that drug release occurs due to a trigger from an environmental stimulus like pH, temperature, etc. [88]. The thermoresponsive graft co-polymeric 5-FU-loaded nanoparticles made from chitosan-g-poly(A -vinylcaprolactam), prepared by an ionic crosslinking method, showed a lower critical solution temperature (LCST) at 38 C, with a prominent in vitro drug release above LCST [89].

A similar methodology was applied by Xiang et al. (2009) for the synthesis of chitosan grafted with poly(L-tryptophan) chains (Scheme 15.22). Deacetylated chitosan (deacetylation degree of amino groups 75%) was employed as a multifunctional macroinitiator for the polymerization of the L-tryptophan-NCA in ethyl acetate solutions leading to the synthesis of chitosan-g-poly(L-tryptophan) graft copolymers. The products were analyzed by NMR and IR spectroscopy.
