Spectroscopic, thermal characterizations and bacteria inhibition of chemically modified chitosan with phthalic anhydride

Chitosan (Ch) is a natural polysaccharide which presents biocompatibility, biodegradability, non-toxicity, mucoadhesion and antimicrobial activity. For instance, the chemical modification using anhydrides have been receiving many attentions for biomedical applications due to the grafting of hydrophobic groups to obtain an amphiphilic molecule. Herein the modified Ch (m-Ch) was obtained by grafting using phthalic anhydride and evaluated their...
