CA 2750252

The present disclosure provides a cross-linked material comprising conjugates which include two or more separate affinity ligands bound to a non-polymeric framework, wherein the molecular weight of the non-polymeric framework is less than 10,000 Da; and multivalent cross-linking agents that non-covalently bind the affinity ligands of the conjugates and thereby cross-link the conjugates to form a cross-linked material, wherein the non-covalent bonds between the multivalent cross-linking agents and the affinity ligands are competitively dissociated in the presence of excess amounts of a target molecule. The present disclosure also provides methods of making and methods of using these materials. In other aspects, the present disclosure provides exemplary conjugates including conjugates for use in glucose responsive cross-linked materials.

La présente invention concerne un matériau réticulé comportant des conjugués qui comprennent au moins deux ligands d'affinité distincts liés à une matrice non polymérique, le poids moléculaire de la matrice non polymérique étant inférieur à 10,000 Da; et des agents de réticulation multivalents qui assurent la liaison non covalente des ligands d'affinité des conjugués permettant ainsi la réticulation des conjugués pour former un matériau réticulé. Les liaisons non covalentes entre les agents de réticulation multivalents et les ligands d'affinité sont dissociés par compétition en présence de quantités excédentaires d'une molécule cible. La présente invention concerne également des procédés de fabrication et des procédés d'utilisation de ces matériaux. Selon d'autres aspects, la présente invention concerne des conjugués représentatifs comprenant des conjugués destinés à être utilisés dans des matériaux réticulés sensibles au glucose.
