High strength pure chitosan hydrogels via double crosslinking strategy

Chitosan (CS) hydrogels have been widely used throughout basic tissue engineering and regenerative medicine research and it is very desirable to develop advanced CS materials with superior mechanical and topographical properties for more extensive applications. Herein, we present the design of a double crosslinking pure CS hydrogel material via the synergic effect of the chemical covalent network, hydrophobic interactions, enhanced...
