NanoComposix’s dried gold nanopowders are formulated with polymer or alkanethiol surface coatings which allow the nanoparticles to easily be redispersed as unagglomerated dispersions in a variety of solvents. We have verified the redispersion with transmission electron microscopy (TEM), UV-visible spectroscopy and dynamic light scattering. For use in applications in diagnostics, biomedical therapies, and plasmonics. Please contact us if you would like other sizes.
