Product Details


  • TORSKAL’s unconjugated gold nanoparticles are made using a unique proprietary protocol resulting in particles with superior size distribution and shape compared to that of the leading competitor.
  • Our gold nanoparticle preparations have a narrow size distribution (SD less than 10%), with excellent reproducibility, and more than 95% spherical particles.
  • All of our batches go through stringent quality control prior to shipment to our customers 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 prolongs the shelf life of the product.
  • Do NOT freeze. Freezing causes irreversible aggregation of the gold nanoparticles.
  • When stored as specified the product is stable for at least six months.
