    Structure of 0.8 nm Nanogold® gold nanoparticle (undecagold) showing the [Au11] core, coordinated ligands and peripheral reactive group (maleimide).
    Amino-Nanogold® 0.8 nm (Positively Charged)

    Selectively label unique sugar or activated carboxyl sites! Positively ionizing amino-groups enable charge-based staining or labeling of negatively charged targets

    Left: Silver-enhanced Nanogold®-labeled K+ channel Kv2.1 subunit in rat brain, X15,000 (J.-H. Tao-Cheng, NIH). Right: Darkfield STEM micrographs of Maleimido Nanogold® labeled A β peptide targeting proteasomes; sample was stained with methylamine vanadate. White dots are 1.4 nm Nanogold®. From Gregori, L., Hainfeld, J.F., Simon, M.N., and Goldgaber, D. (1997). Binding of amyloid beta protein to the 20S proteasome. J. Biol. Chem. 272, 58-62.
    Amino-Nanogold® 1.4 nm (Positively Charged)

    Selectively label unique sugar or activated carboxyl sites! Positively ionizing amino-groups enable charge-based staining or labeling of negatively charged targets

    Unconjugated 12 nm Nanogold®, showing monodisperse, highly regular, spherically symmetrical 12 nm gold core and uniform, consistent ligand coating. This ensures a highly regular particle size and reliable, reproducible labeling and EM results.
    new-solidAmino-Nanogold® 12 nm (Positively Charged)

    Selectively label unique sugar or activated carboxyl sites! Positively ionizing amino-groups enable charge-based staining or labeling of negatively charged targets

    Unconjugated 5 nm Nanogold®, showing monodisperse, highly regular, spherically symmetrical 5 nm gold core and uniform, thin and consistent ligand coating. This ensures a highly regular particle size, smaller probe size, and reliable, reproducible labeling and EM results.
    new-solidAmino-Nanogold® 5 nm (Positively Charged)

    Selectively label unique sugar or activated carboxyl sites! Positively ionizing amino-groups enable charge-based staining or labeling of negatively charged targets

    Kidneys in live mouse after IV injection of AuroVist™ 1.9nm. Kidney function is visualized as small gold nanoparticles are filtered from the blood, passing through glomeruli, tubules and into ureters. Taken with a mammography unit (8 mA.sec, 22 kVp).
    AuroVist 1.9 nm Gold Nanoparticle Xray Contrast Agent for Micro CT

    Ultra-high resolution xray contrast agent with 1.9 nm gold nanoparticles. Image kidneys, organs, tumors… in vivo vascular casting!

    20µm blood vessels in a live mouse around legs and pelvic region after IV injection of AuroVist™-15nm.
    AuroVist 15nm Gold Nanoparticle Xray Contrast Agent for Micro CT

    24-hour blood pool xray contrast agent for micro-CT. Gold nanoparticle technology for tumor loading and vascular research.

    Structure of 0.8 nm Nanogold® gold nanoparticle (undecagold) showing the [Au11] core, coordinated ligands and peripheral reactive group (maleimide).
    Carboxyl-Nanogold® 0.8 nm (Negatively Charged)

    Precision Nanogold® labels, covalently bound to multiple carboxyls, allowing easy targeting of positively charged targets.
