Cover Story: Block copolymer-based magnetic-responsive membranes are smart membranes which due to the presence of iron oxide nanoparticle are susceptible to magnetic stimuli exhibited by a change in their porous structure. One of the hallmarks of these hybrid materials is to mitigate fouling, a primary membrane separation-related issue. This work demonstrates the use of these novel membranes, synthesized via reversible addition–fragmentation chain transfer polymerization. The impact of the magnetic responsiveness of hybrid membranes on protein permeation was evaluated under ON/OFF cyclic magnetic field conditions, using bovine serum albumin as the model protein. The magnetic field allowed for a lower decay of the permeate flux and an improved protein transmission, suggesting the potential contribution of these magnetic-responsive block copolymer membranes for the development of improved bioseparations.
