Product Details


  • TORSKAL’s unconjugated gold nanoparticles are produced utilizing a patented procedure that produces particles with better size distribution and form than the competitor’s.
  • Our gold nanoparticle preparations feature a small size distribution (SD less than 5%), with excellent reproducibility, and over 95% spherical particles.
  • Before being shipped to our customers, all our batches go through a rigorous quality control process that using Dynamic Light Scattering (DLS), Transmission Electron Microscopy (TEM), and UV-Vis to ensure size and monodispersity, as well as other parameters.



  • Store product away from direct sunlight at 4-8°C. Lower temperature extends the shelf life of the product.
  • Do not freeze. Freezing causes irreversible aggregation of the gold nanoparticles.
  • The product is stable for at least six months when stored as directed.
