Nanoprobes develops and manufactures functionalized gold nanoparticles, immunogold conjugates and gold labeling reagents for biomedical research and imaging. Products include Nanogold® functionalized gold nanoparticles for labeling and conjugation, antibody and protein conjugates, and our combined fluorescent and gold immunoprobes, FluoroNanogold™. In addition, we offer AuroVist™, the only gold nanoparticle contrast agent for micro CT, and a variety of other staining, imaging and detection reagents for research, imaging and diagnostics applications.  

Custom gold nanoparticle manufacture, conjugation, and applications development for diagnostics, pharmaceuticals or nanomaterials are also available. Contact technical support with inquiries. 

Our products include: 

Nanogold® 1.4 nm gold nanoparticle labeling reagents for labeling antibodies, proteins, peptides, oligonucleotides or other molecules to create targeted probes. 


Nanogold® Labeling Reagents


Recently added: our 1.4 nm and 5 nm Nanogold Click reagents for bioorthogonal labeling of azides and alkynes: 


5 nm Nanogold Click Reagents


Nanogold® antibody and streptavidin conjugates for electron microscopy and structural biology research. 


Nanogold®-Fab' labeling


Silver and gold enhancers for electron and light microscopy with Nanogold® and colloidal gold probes.


 GoldEnhance™: how it works 


FluoroNanogold™, a unique combined fluorescent and gold immunoprobe for checking labeling by fluorescence before electron microscopy specimen prep, and for correlative light and electron microscopy.
