Gold nanorods offered at 1 OD or 50 OD (high) concentration with peak resonance options of 660 nm, 800 nm, and 980 nm.

• For use in diagnostics, photothermal therapies, imaging, drug delivery, and more.
• High quality nanoparticles, precisely engineered and highly characterized
• Unagglomerated and monodisperse
• CTAB-free
• Citrate surface is stable and displaceable
• PEG surface offers biocompatibility
• Carboxyl surface is ideal for conjugation

The Citrate surface is stable and displaceable for easy functionalization with silica, DNA, and antibodies. The PEG surface offers high stability, compatibility with some alcohols, and biocompatibility. The Carboxyl surface can be used for conjugation to proteins, antibodies, and other biomolecules via EDC/NHS chemistry.

All gold nanorods from nanoComposix are CTAB-free and provided in water. Many gold nanorods available commercially are coated with cetyl trimethylammonium bromide (CTAB), a common surfactant used during nanorod synthesis. CTAB coated nanorods are toxic in biological systems and are readily destabilized when transferred to different solvents. NanoComposix’s gold nanorods are CTAB-free and highly purified to remove residual reactants following synthesis. Gold nanorods have used in optical filters, rapid diagnostics like Lateral Flow Immunoassays, sensing and biosensing devices, photothermal therapies, and many other applications.

Each batch is extensively characterized to meet highest quality standards, ensuring reliable and reproducible results. All products supplied with batch-specific COA's with TEM, DLS, Zeta, and UV-Vis.

Colloidal gold has applications in Diagnostics, Lateral Flow Assays, Molecular Detection, Photothermal and Microwave-based Therapies, TEM labels, Nanotoxicology, Plasmonics (SPR / Surface Plasmon Resonance), and novel Color Enhancements and Pigments.
