About Spherotech
Spherotech was established in 1992 to manufacture and supply uniform monodispersed micro and nanoparticles for biomedical applications, diagnostics and drug discovery. Our headquarters is located 25 miles north of Chicago, in Lake Forest, IL.

As a global supplier of micro and nanoparticle solutions, our skilled scientists can manufacture high quality polystyrene fluorescent, paramagnetic, ferromagnetic and color dyed particles. In addition, we prepare gold nanoparticles for diagnostic applications.

Spherotech offers:

  • Monodispersed uniform sized particles for functional assays
  • Different types of functionalized beads for covalent and passive couplings
  • Precoated beads with antibodies, proteins and ligands
  • Cross linked beads for more functional groups and organic reactions
  • Beads in different sizes for flow cytometry alignment, calibration, compensation, counting and sorting

Spherotech micro and nanoparticles applications:

  • Fluorescence microscopy
  • Genomic and Immunoassays
  • EIA and ELISA assays
  • Flow cytometry
  • DNA isolation and bead PCR
