Abstract
A disposable, virus-trapping membrane, and a corresponding method to remove viruses from solution are described. The membrane includes a disposable, micro-porous filter membrane and a ligand immobilized on the membrane. The ligand irreversibly and selectively binds viruses. The ligand also has a pKa sufficiently high to repel antibodies via electrostatic charge repulsion.
