In one aspect, the disclosure provides cross-linked materials that include multivalent lectins with at least two binding sites for glucose, wherein the lectins include at least one covalently linked affinity ligand which is capable of competing with glucose for binding with at least one of said binding sites; and conjugates that include two or more separate affinity ligands bound to a conjugate framework, wherein the two or more affinity ligands compete with glucose for binding with the lectins at said binding sites and wherein conjugates are cross-linked within the material as a result of non-covalent interactions between lectins and affinity ligands on different conjugates. These materials are designed to release amounts of conjugate in response to desired concentrations of glucose. Depending on the end application, in various embodiments, the conjugates may also include a drug and/or a detectable label.
在一个方面,该公开提供了包括多价凝集素的交联材料,其中该多价凝集素具有至少两个葡萄糖结合位点,其中该凝集素包括至少一个与亲和配体共价连接的亲和配体,该亲和配体能够与至少一个所述结合位点中的葡萄糖竞争结合;以及包括绑定到共轭框架的两个或更多个独立亲和配体的共轭物,其中这两个或更多个亲和配体与葡萄糖在所述结合位点上与凝集素竞争结合,其中由于不同共轭物上的凝集素和亲和配体之间的非共价相互作用,共轭物在材料内交联。这些材料旨在根据所需葡萄糖浓度释放共轭物的量。根据最终应用,在各种实施例中,共轭物还可以包括药物和/或可检测标记。
