Prof. Baolin Guo of FIST has made achievement on construction method of Physical Dynamic Double-Network Hydrogels, and published an academic paper in Nature Protocols, a high-profile journal in materials field. In this article, the approach combines the use of ureido–pyrimidinone hydrogen bonding with metal-coordination interactions between Fe3+ and catechol groups, thereby generating double physical cross-linked hydrogels. And the hydrogels have fast self-healing properties, high mechanical strength and can be tuned to respond to conditions such as temperature, pH and light. When used as dressings, the hydrogels facilitate tissue repair in vivo.
Their work has been supported by the National Natural Science Foundation of China, State Key Laboratory for Mechanical Behavior of Materials, and the World-Class Universities (Disciplines) and the Characteristic Development Guidance Funds for the Central Universities. The first unit of the article is FIST of XJTU.
