The new technology enables the covalent bonding of functional groups to the surface of magnetic particles. The particles, with diameters below 50 nm, achieve magnetic moments 5x exceeding the moment of ironoxide beads and 10x exceeding the moment of dynabeads.

It is our goal to create innovative solutions to magnetic separation on any application scale – from microreactor to pilot scale and industrial fabrication.
