fluidMAG

fluidMAG-nanoparticles are ferrofluids consisting of an aqueous dispersion of magnetic iron oxides with diameters of 50 nm, 100 nm and 200 nm. 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.

Application: Cell separation, MRI-diagnostics, Magnetic Drug-Targeting
Formulation: suspension in ddH2O, autoclaved
Concentration: 25 mg/ml
Particle sizes: 50 nm, 100 nm, 200 nm; ( 75 nm, 150 nm on request)

fluidMAG-nanoparticles with hydrodynamic diameters of 100-200 nm have a multi-domain core and in-batch separable by a external magnetic field (magnetic separator). Therefore, a fast and easy magnetic isolation of nanoparticles is possible.

Ferrofluids with particle sizes of 50 nm have a single domain core and therefore not separable by an external magnetic field. These substances are real magnetic fluids, and the magnetic isolation is only possible with a High Gradient Magnetic Separator (e.g. Miltenyi® separation columns). This is expensive and time consuming; therefore we recommend using magnetic nanoparticles with a minimum size of 100 nm.
