Chitosan based microgels
Web2 hours ago · Chitosan (CS) is a repetitive unit polymer of cationic (1-4)-2-amino-2-deoxy-β-D-glucan. CS has the distinctive feature of carrying predominant units of amino groups, making it wear more cationic charges. Such groups can behave as cationic in acidic media, leading to it often display polyelectrolyte behavior in solution [ 30 ].
