A composition includes a biodegradable hydrogel that includes a hydrogel forming base polymer and a plurality of physiologically degradable ester linkages, amide linkages, azide-alkyne cycloaddition linkages, acrylate-thiol linkages, urethane linkages, and/or methacrylate-thiol linkages, a polynucleotide coupling polymeric molecule; and a polynucleotide. The polynucleotide is released under physiological conditions in a spatial and/or temporally controlled or predetermined manner from the composition.
一种组合物包括可生物降解的水凝胶,该水凝胶包括水凝胶形成基础聚合物和多种生理降解的酯键、酰胺键、偶氮-炔环加成键、丙烯酸基-硫醇键、脲键和/或甲基丙烯酸基-硫醇键,以及与多核苷酸耦合的聚合分子;和多核苷酸。在生理条件下,该多核苷酸以空间和/或时间受控或预定的方式从该组合物中释放出来。
