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.
A wipe article includes a substrate, a cationic coating disposed on a surface of the substrate, distributed throughout the substrate, or both. The cationic coating contains a guanidinyl-containing polymer that is crosslinked and bound to the substrate. The substrate includes sponge, nonwoven fabric, or woven fabric. The wipes are useful for removing microorganisms from a microorganism-contaminated surface and also for reducing re-contamination of the cleaned surface or transfer to another surface of the removed microorganisms.
