Abstract
Methods are provided for the use of magnetically responsive particles in systems in which the separation of certain molecules, macromolecules and cells from the surrounding medium is desirable. The magnetically responsive particles may be coupled to a wide variety of molecules. The magnetic particles can be dispersed in aqueous media without rapid settling and conveniently reclaimed from media with a magnetic field. Preferred particles do not become magnetic after application of a magnetic field and can be redispersed and reused.
