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.

TEM-multi-domain magnetite core
TEM-single-domain magnetite cores
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.
nano-screenMAG - are fluorescent magnetic nanoparticles based on our approved fluidMAG particle technology.
| Application: | Cell separation, MRI-diagnostics, Magnetic Drug-Targeting | |
| Concentration: | 25 mg/ml | |
| Particle sizes: | 100 nm, 150 nm, 250 nm | |
| Price: | 1 ml - 55 EURO / 73 US$ | 5 ml - 220 EURO / 289 US$ |

These particles consist of a magnetite core which is first covered
by a lipophilic fluorescence dye.
A second layer is used to offer all the functional groups on the outer
surface as with the fluidMAG particles.

Due to the additional fluorescence layer it is not possible to synthesize nano-screenMAG particles smaller than 100 nm.
