Our separation system consists of a structured array of iron wires in a flow cell which generates an IMF and preferentially retains larger nanoparticles while allowing smaller particles to flow through. We performed particle tracking simulations to understand the variation of non-magnetic particle motion with size in the presence of a wire array.
