A thermosensitive hydrogel of chitosan/poly vinyl alcohol(CTS/PVA) containing drug-loaded particles was prepared.The influences of drug-loaded particles on the properties of hydrogel were investigated.The experimental results show that the strength of the hydrogel containing drug-loaded particles is almost the double of that of the simple CTS/PVA blending hydrogel.The burst-release behavior is not observed in the drug release experiment.Instead
the release rate is slow and stable
and the cumulative release of BSA is only 32% after 14 days.
