Abstract

The invention provides polymer-grafted and functionalized nonwoven membranes adapted for use in bioseparation processes, the membranes including a nonwoven web of polyester fibers having an average fiber diameter of less than about 1.5 microns, each of the plurality of polyester fibers having grafted thereon a plurality of polymer segments constructed of a methacrylate polymer, each polymer segment carrying a functional group adapted for binding to a target molecule. The invention also provides a method of bioseparation comprising passing a solution comprising the target molecule, such as a protein, through the nonwoven membrane of the invention such that at least a portion of the target molecule in the solution binds to the nonwoven membrane. A method for preparing a polymer-grafted and functionalized nonwoven membrane adapted for use in bioseparation processes is also provided.
