Description Application Owing to their plasmonic properties nanoparticles of gold and silver find broad range of applications extending from diagnostics to molecular detection, photothermal and microwave-based therapies, and nanotoxicology. Colloidal silver nanoparticles also find applications in antimicrobial coatings, electronics and photovoltaics, and surface enhanced Raman spectroscopy (SERS) whereas the colloidal gold nanoparticles find applications in lateral flow assays (immunochromatographic assays) and as TEM labels and size standards. Our Econix gold nnanospheres contain PVP (40 kD polyvinylpyrrolidone) as excipient. The PVP provides strong steric stability to the gold nanospheres. The Econix gold nanospheres are unagglomerated and low cost, and are ideal for applications requiring large quantities. Storage and Stability DO NOT FREEZE. Store at 2-8C when not in use to maximize shelf life. Nanomaterials can be sensitive to high and low pH conditions and high salt concentrations. Use caution when changing environmental conditions as particles may aggregate. Legal Information Product of nanoComposix, Inc.
