Amine Gold Nanoparticles

We are available with 5nm, 10nm, 15nm,.......100nm, in PEG2000-SH  and PEG5000-SH.

Amine functionalized gold nanoparticles have precisely engineered surface chemistry that allows for simple and efficient binding to moieties that react with primary amines.

An example of such a reaction would be a conjugation to a protein or antibody that has been tagged NHS, which would yield a covalent link between the gold nanoparticle surface and the protein.

This permanent linkage allows for further downstream applications such as monitoring the distribution of the now-tagged molecule.

  • Amine Gold Nanoparticles are made using a unique proprietary protocol resulting in particles with superior size distribution and shape compared to the leading competitor.
  • These gold nanoparticles have a narrow size distribution (CV of less than 15%) and more than 95% spherical particles.
  • Low batch to batch variability (+/- 2nm) assures you as a customer always end up with a product within the specified size range ordered.
  • All of our batches go through stringent quality control prior to shipment to our customers using dynamic light scattering to guarantee size and monodispersity and lot specifications are supplied with each product.


Store product away from direct sunlight at 4°C. Do NOT freeze. When stored as specified the product is stable for at least twelve months.
