A substrate comprising a crosslinked polymer primer layer, and grafted thereto a ligand-functionalized polymer is provided. The grafted polymer has the requisite affinity for binding neutral or negatively charged biomaterials, such as cells, cell debris, bacteria, spores, viruses, nucleic acids, and proteins, at pH's near or below the pI's of the biomaterials.
提供了一种基底,它包括一个交联聚合物底漆层,并在其上接枝了一个配体功能化聚合物。接枝的聚合物具有必要的亲和力,可以在生物材料的pH值接近或低于其等电点时结合中性或负电荷的生物材料,例如细胞、细胞碎片、细菌、孢子、病毒、核酸和蛋白质。
