In this study, self-healing hydrogels were created using oxidized hydroxybutanoyl glycan (OHbG) and quaternized carboxymethyl chitosan (QCMCS), displaying antioxidant antibacterial properties for pH-responsive drug delivery. The structures of the modified polysaccharides confirmed through 1H NMR analysis. Double crosslinking in hydrogel occurred via imine bonds (between aldehyde group OHbG amine QCMCS) ionic interactions carboxyl QCMCS). exhibited improved thermal stability with an increase concentration. OHbG/QCMCS demonstrated high compressive strength, significant swelling, large pore size. Drug release profiles varied between pH 2.0 (96.57%) 7.4 (63.22%). Additionally, displayed effects without compromising polysaccharides’ inherent characteristics. No cytotoxicity was observed any samples. These findings indicate that is a biocompatible stimuli-responsive carrier, potential various pharmaceutical, biomedical, biotechnological applications.
