Liquid or Dry?

In order to prevent nanoparticle aggregation, most nanoparticles are sold as a suspension in a liquid. Recently, we have developed methods to freeze dry (lyophilize) nanoparticles into a powder. The powder format has a number of advantages including:

  • Multi-year shelf life
  • Can be resuspended in a variety of different solvents
  • Can be prepared at a very high concentration
  • Once resuspended, has a consistent free-ion concentration

Dried powders are available as standard products for many of our gold and silver particles. Other dried formulations of nanoparticles are available on request.
