Melamine resin particles, Red-fluorescent (MF-FluoRed): Ex/Em 636 nm/686 nm

Monodisperse fluorescently labelled melamine resin particles were introduced by microParticles GmbH as a new and versatile product family in the late 1990’s. They are prepared by an acid-catalyzed polycondensation process in aqueous solution using melamine resin precursors in presence of various fluorophores. The particles have excellent properties such as high monodispersity (CV < 5 %), spherical shape, high optical transparency, high mechanical, thermal, and chemical stability, strong fluorescence, and high refractive index (1,68). They can be produced with blue, green, orange, and red fluorescence in a wide diameter range with different fluorescence intensities as well as with a variable surface chemistry/functionality. The fluorescently labelled MF microspheres have the additional advantage of being stable in common organic solvents and oils without any dyeleaching, swelling, or shrinking. Our Red-fluorescent melamine resin particles are available in a range of discrete sizes from 500 nm to 12 µm and can be delivered as a 2,5 % w/v aqueous suspension or as dry powders                         (for sizes > 1 µm).
