Particle Development for Next-Level Innovation

Our Expertise

At microParticles GmbH, we’re a passionate team of scientists and technical experts with over 30 years of experience in colloid and polymer chemistry, particle synthesis, and surface functionalization.

We specialize in the development of monodisperse microspheres made from poly(styrene), poly(methyl methacrylate), melamine resin and silica—available in a wide range of diameters to meet the demands of research and industry.

Our portfolio includes:
  • Certified particle size standards
  • Paramagnetic beads
  • Dyed and fluorescent microspheres
  • Metal-coated particles
  • Chemically and biochemically functionalized surfaces
certified particle standard
monodisperse micropheres

microParticles GmbH provides high-precision certified particle size standards designed for the calibration, validation, and performance testing of particle sizing instruments.

Our standards are:
  • Monodisperse polymer and silica microspheres with ultra-narrow size distributions
  • Traceable according to NIST (National Institute of Standards and Technology) and CRM (Certified Reference Materials) traceable through the Joint Research Center (JRC) of the European Commission
  • Calibrated using particle sizing techniques, including: Disc-Stack Cetrifugation (CPS Disk Centrifuge), Impedance measurement (Multiszer4E)

Fluorescent Microspheres with strong, stable fluorescence across a broad spectral range—from UV to NIR.

The advantage of our particles:
  • high monodispersity
  • high photostability, and are
  • compatible with aqueous and organic media –

These particles ideal for bioimaging, diagnostics, and therapeutic platforms.

In parallel, we can now also offer :

monodisperse, spherical silica particles up to a size of 100 µm and beyond in the microParticles GmbH product portfolio. These particles are characterized by a very narrow size distribution (CV < 5%) and a smooth morphology with optional surface functionalization.
