nano-screenMAG - is an aqueous dispersion of magnetic-fluorescent nanoparticles available in hydrodynamic diameters of 100 nm, 150 and 200 nm.

nano-screenMAG particles consist of a magnetite core which is first covered by a lipophilic fluorescence dye. A second layer envelops the particle with a hydrophilic polymer which protects the particles 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.

FluorescenceType
Fluorescence Color Excitation Emission
nano-screenMAG/B blue 378 nm 413 nm
nano-screenMAG/G green 476 nm 490 nm
nano-screenMAG/O orange 524 nm 539 nm
nano-screenMAG/P pink 547 nm 581 nm
nano-screenMAG/R red 578 nm 613 nm

NOTE: The fluorescence of the nano-screenMAG particles is only detectable on the same side where the excitation takes place.

Please note that there is a difference in fluorescence observation between dissolved fluorescence molecules and solid fluorescence particles. Fluorescence spectrophotometer with a fluorescence detection unit with an angle of 90° to the excitation source will detect no or only weak fluorescence signals.
