    • 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,本公开提供了交联材料,其包括具有至少两个葡萄糖结合位点的多价凝集素,其中所述凝集素包括至少一种共价连接的亲和配体,其能够与葡萄糖竞争与至少一个所述 结合位点; 和缀合物,其包含与缀合物框架结合的两个或更多个分离的亲和配体,其中两个或更多个亲和配体与葡萄糖竞争与所述结合位点处的凝集素结合,并且其中缀合物在材料内交联, 在不同共轭物上的凝集素和亲和配体之间的共价相互作用。 这些材料被设计成响应于所需浓度的葡萄糖释放结合物的量。 根据最终应用,在各种实施方案中,缀合物还可以包括药物和/或可检测标记。
