PMMA Nanobeads

Our PMMA (Polymethylmethacrylate) based nanospheres are available in sizes between 100 nm to 500 nm. They are characterized by a narrow particle size distribution (see adjacent SEM image) and an excellent lot-to-lot reproducibility. Latex beads with carboxy, aldehyde and plain surfaces for immobilization of biomolecules (proteins, antibodies, haptens, etc.) are available.


We offer a large range of different PMMA nanoparticles suitable for nanobead based technologies, including:

  • Immunoturbidimetric assays
  • Nephelometric assays
  • Solid phase immunoassays
  • Calibration (e.g. flow cytometry, fluorescence microscopy)

Available characteristics

Choose from a wide range of different combinations of size, fluorescence encoding and surface modifications:

We are looking forward to your inquiry.


Please note, that PolyAn also produces customized nanoparticles which incorporate fluorophores for other spectral ranges. All PMMA Nanobeads are available in sizes between 100-500 nm. Custom modifications are available upon request. Please do not hesitate to contact us to get some of our PMMA-Nanobeads!
