The present invention pertains to the design and application of a supramolecular hydrogel having a three-dimensional, self-assembling, elastic, network structure comprising non-polymeric, functional molecules and a liquid medium, whereby the functional molecules are noncovalently crosslinked. The functional molecules may be, for instance, anti-inflammatory molecules, antibiotics, metal chelators, anticancer agents, small peptides, surface-modified nanoparticles, or a combination thereof. The design of the hydrogel includes: 1) modifying functional molecules to convert them into hydrogelators while enhancing or maintaining their therapeutic properties and 2) triggering the hydrogelation process by physical, chemical, or enzymatic processes, thereby resulting in the creation of a supramolecular hydrogel via formation of non-covalent crosslinks by the functional molecules. Applications of the present invention include use of the supramolecular hydrogel, for instance, as a biomaterial for wound healing, tissue engineering, drug delivery, and drug/inhibitor screening.
本发明涉及一种超分子水凝胶的设计和应用,其具有三维自组装、弹性、网络结构,包括非聚合的功能分子和液体介质,其中功能分子是非共价交联的。这些功能分子可以是抗炎分子、抗生素、金属螯合剂、抗癌剂、小肽、表面修饰的纳米粒子或它们的组合。水凝胶的设计包括:1)将功能分子改造成水凝胶剂,同时增强或保持其治疗性能;2)通过物理、化学或酶促过程触发水凝胶化过程,从而通过功能分子的非共价交联形成超分子水凝胶。本发明的应用包括将超分子水凝胶用作生物材料,例如用于伤口愈合、组织工程、药物输送和药物/抑制剂筛选。
