Abstract
Guanidinyl ligand-functionalized polymers, methods of making the same, and substrates bearing a grafted coating of the ligand-functional polymers are described. The grafted polymer has the requisite affinity for binding neutral or negatively charged biomaterials, such as cells, cell debris, bacteria, spores, viruses, nucleic acids, endotoxins and proteins, at pH's near or below the pI's of the biomaterials.
