Superparamagnetic means that the Dynabeads magnetic beads exhibit magnetic properties when placed within a magnetic field, but have no residual magnetism when removed from the magnetic field.
This means that your targeted cells, proteins, or nucleic acids are only subjected to magnetic forces during the time the beads are on the magnet. The beads do not aggregate, but remain evenly dispersed in suspension.
