Nanoprobes Gold Nanoparticles: Nanogold Labels for Imaging & Microscopy
Updated: March 31, 2020
- Novel Coronavirus (COVID-19) resoponse: Nanoprobes continues to accept orders and we will respond to questions and inquiries, but shipping will be carried out on a restricted schedule. Nanoprobes is committed to maintaining a safe, disease-free workplace for our team, partners and customers. In accordance with the New York on Pause directive, we are working remotely except to perform essential tasks. Product shipping will be carried out on a restricted schedule once or twice each week to ensure that our premises remain safe and minimize risk to our team, so you may receive your order one or two days later than you normally would.
Please contact us by email: while these restrictions are in place, we can respond more quickly if you use email rather than phone or fax to contact us. For orders and ordering questions, email us at [email protected]. For technical support, email [email protected]. If you require immediate technical support by phone, call our main number, (631) 205-9490 (toll-free 1-877-447-6266 in the US or Canada). Faxes should be sent to (631) 980-3608.
While the Novel Coronavirus outbreak continues, we will follow advice from the Centers for Disease Control, World Health Organization and New York State Department of Health. If our situation changes, we will post an update here.
- We are currently unable to ship directly to Japan. If you wish to order products for shipment to Japan, please contact one of our International Distributors for Japan.

As we develop nanoparticle products for the scientific community,
we strive to engineer the most sensitive reagents
and nanotechnology for detecting biological molecules.
Our unique gold nanoparticle labeling technology uses chemically cross-linked metal clusters and nanoparticles as labels.
Unlike conventional immunogold probes, in which colloidal gold particles are electrostatically adsorbed to antibodies and proteins, our gold nanoparticle labels are uncharged molecules which are cross-linked to specific sites on biomolecules. This gives our nanogold probes greater range and versatility than colloidal gold.
Our labels can be attached to any molecule with a reactive group -- proteins, peptides, oligonucleotides, small molecules and lipids -- for detection and localization. Other labels can be combined with our gold particle labels; our unique FluoroNanogold probes combine Nanogold® and fluorescein into a single probe for imaging a specimen both by fluorescence and electron microscopy. Our gold nanoparticles, including our Nanogold™ conjugates, and Nanogold™ labeling reagents, are formulated for use with electron microscopy (tem) as well as light microscopy, immunolabeling, x-ray contrast for EM, angiography, mammography and microCT, and for correlative and fluorescence microscopy imaging.
New probes can be engineered based on any fragment of a naturally occurring biomolecule, and the label can be positioned away from the binding site so it does not interfere with binding.
Our Nanogold® probes have been cited in over 250 publications, and are used in the laboratories of several Nobel Laureates.
It's all about creating better tools and finding innovative solutions,
so that research and treatments can move ahead.
