Magnetofluid-nanoparticles are ferrofluids consisting of an aqueous dispersion of magnetic iron oxides with diameters
of 50nm, 100nm and 200nm. The particles are covered with hydrophilic polymers which protect them against
aggregation by foreign ions. Terminal functional groups such as ion-exchange groups or reactive groups for covalent
immobilization can be used for binding to biomolecules. Ferrofluids can further be used for MRI-diagnostics and
magnetic drug targeting applications.
