Abstract
Devices and methods for label-free separation of material. A fluid-filled settling chamber is used for settling material by gravity. A fluid mixture comprising a target material and at least one non-target material is introduced into the settling chamber, where the target material has a paramagnetic property. A magnetic field is applied to the settling chamber sufficient to impede gravitational settling of the target material and not affect gravitational settling of the non-target material, in order to separate the target material from the non-target material.
