  • Product Group Details

Bare Gold Nanorods -These bare particles are the industry standard in size accuracy, shape consistency, shelf life stability, and reactivity. This product is completely purified in DI water where CTAB has been minimized. This product come in two different concentrations; 0.05mg/mL standard and 5mg/mL concentrated. This product comes with two different ligand options with positive and neutral zeta potentials. This product may also be radiation sterilized and endotoxin purified. Every delivery comes with a Certificate of Analysis that includes a TEM image and UV VIS spectrum. All items are in stock and are shipped the same day for next day delivery.

Conjugated Gold Nanorods - Highly protected covalent polymer layer for a wide variety of pH and salt environments. Popular conjugations (amine, biotin, carboxyl, methyl, neutravidin, streptavidin), antibodies, secondary antibody conjugates, and oligos. For use in dark field imaging, heterogeneous diagnostics including lateral flow assays, ELISA, and more.

Customer Designed Gold Nanorods - Customers define their covalent or charge induced conjugation. This product comes completely purified in the buffer chosen at two concentrations choices, 2.5mg/mL and 12.5mg/mL. This product may also be radiation sterilized and endotoxin purified. Every delivery comes with a Certificate of Analysis that includes a TEM image and UV VIS spectrum. Concentration, charge, and size are also determined by NIST traceable DLS, TEM, and UV-VIS. All conjugate loading is experimentally analyzed and included on the COA.

Zero Order Diagnostics - Short length covalent polymer layer to take advantage of SPR shifting. Popular conjugations, antibodies, secondary antibody conjugates, and oligos.

Conjugated Gold Nanorods for in vivo - Covalent polymer layer for use in vivo providing ultra long circulation times. Customers have can have their antibodies conjugated to these particles.

Molecular Surface Modified Gold Nanorods - Alkyl thiol and other SAM modified gold nanorods for analytical applications.

Nsol™ Gold Nanorods in Organic Solvents - Organic capped gold nanoparticles for use in a wide variety of organic solvents.

One-Step Kits: Gold Nanorods for Antibody Conjugations - Utilizing our patent pending technology, customers are provided 2.5mg of 25nm diameter gold nanorods for one step conjugation to any antibody. A covalently bound polymer layer protects the gold from a wide range of pHs and salts and ensures a covalent bound antibody.
