Hydrogels have been used for many applications due to its unique and desirable properties. And those characteristics and applications of the gels are closely related to their preparation methods. In this study, we introduced boronic acid (BA) into alginate backbone for specific binding between BA and diol group in alginate and successfully prepared hydrogel by its own component without adding any other cross-linkers. The hydrogel showed high sensitivity to pH change due to the pH responsibility of the BA-diol interactions. Furthermore alginate-BA gel prepared under specific conditions showed interesting mechanical properties such as sol-gel transition, adhesiveness, self-healing, re-shaping, superior elongation. We expect that these excellent mechanical properties and specific binding with diol can be used for biomedical applications. |
