fluidMAG

fluidMAG-nanoparticles are ferrofluids consisting ofan aqueous dispersion of magnetic iron oxides with diameters of 50 nm,100 nm and 200 nm. The particles are covered with hydrophilic polymerswhich protect them against aggregation by foreign ions. Terminalfunctional groups such as ion-exchange groups or reactive groups forcovalent immobilization can be used for binding to biomolecules.Ferrofluids can further be used for MRI-diagnostics and magnetic drugtargeting 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)

TEM-multi-domain magnetite core

TEM-single-domain magnetite cores

fluidMAG-nanoparticles with hydrodynamicdiameters of 100-200 nm have a multi-domain core and in-batch separableby a external magnetic field (magnetic separator). Therefore, a fastand easy magnetic isolation of nanoparticles is possible.

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