Abstract (en)
[origin: WO03038842A1] The invention relates to a method for producing composite particles in which superparamagnetic iron oxide particles having a diameter of less than 30 nm are contained in a polysiloxane matrix comprising functional groups. The composite particles obtained by the method are suitable for magnetic separation methods.
