Abstract
Embodiments herein are directed to a system and a method of selectively manipulating magnetically-barcoded materials from background magnetic materials. Magnetic barcodes include layers of magnetic anisotropy. These are then manipulated by a magnetic system that can drive spatio-temporal magnetic fields that can 'match' a barcode to drive a specific interaction, thereby providing a “lock-key” interaction. This technique is able to selectively manipulate magnetically-barcoded materials, and can have applications across a variety of magnetic systems such as cell separation, drug delivery, valves, and motors.
