Abstract A series of hydrogels with different ratios of chitosan and licorice polysaccharide (LP) were prepared by crosslinking to different concentrations of genipin (gp). They were characterized by FTIR (Fourier transform infrared
spectroscopy), SEM (Scanning electron microscope), swelling ratio, rheological
measurements, degradation with time, cytotoxicity, and antibacterial efficacy.
Results show that the hydrogels have porous structures. With an increase in LP
content, the swelling rate grows in the early stage of immersion in buffer and
drops later. The swelling ratio ranged from 986% to 1677%, and stiffness varied
from 777 Pa to 1792 Pa. The addition of LP reduced the mechanical… More >
