Abstract
Devices, methods, and systems are provided for extracting particles from a ferrofluid. Such methods may comprise receiving a flow of ferrofluid comprising target particles and background particles and generating a first, focusing magnetic field to focus the target particles towards a capture region. The capture region may capture the target particles and a plurality of background particles. A second, defocusing magnetic field may be configured to remove background particles from the capture region. A detector may be used to detect the target particles bound to the target region.
