Abstract: 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.

Abstract: A method of purifying a biological composition includes: disposing loose cationic ligand-functionalized staple fibers and a biological composition within a mixing volume of a vessel; agitating the biological composition and the loose cationic ligand-functionalized staple fibers while they are in intimate contact with each other within the mixing volume to provide modified fibers and a purified biological composition; and separating at least a portion of the purified biological composition from the modified fibers and any loose cationic ligand-functionalized staple fibers with which it is in contact. The loose cationic ligand-functionalized staple fibers have a modified surface layer comprising a grafted acrylic polymer comprising 10 to 100 percent by weight of a cationically-ionizable monomer unit. An article for purifying a biological composition includes: a vessel having a mixing volume disposed therein; and the loose cationic ligand-functionalized staple fibers disposed within the mixing volume.

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.
