Fluorescent Functionalized Particles

microParticles GmbH provides a broad selection of monodisperse fluorescent microparticles based on polystyrene (PS), silicon dioxide (SiO₂), poly(methyl methacrylate) PMMA, and melamine formaldehyde (MF). These particles are engineered with precise size control and are available with a variety of surface functionalizations to support targeted interactions in research and industrial applications.

Surface Functionalization Options

Standard and custom surface chemistries enable compatibility with a wide range of biomolecules and materials.

Standard groups:

Carboxyl (-COOH)
Amino (-NH₂)
Streptavidin (-SA)

Custom modifications (on request):

Sulfonic acid
Maleimide
Hydroxyl (-OH)
Epoxy

The Particles are offered with following excitation/emission profiles:

Color	Excitation [nm]	Emmission [nm]
Color
Blue	360 – 400	415 – 450
Green	460 – 490	510 – 550
Orange	500 – 530 530 – 560	560 – 580 580 – 600
Red	580 – 610 630 – 650	610 – 650 660 – 700
