BioPure Gold Nanorod

NANOXACT GOLD NANORODS – BARE (CITRATE)

DESCRIPTION

NanoComposix’s gold nanorods are surface plasmon resonant (SPR) rod-shaped nanoparticles with narrow size distributions and uniform shape. The gold nanorods have absorption peaks that are tunable throughout the visible and short wave near-infrared (SWNIR) regions of the electromagnetic spectrum. Our purification methods remove ammonium surfactants used during synthesis and replace it with citrate, producing a stable, easily displaceable surface chemistry to use as a base for functionalization with a wide variety of molecules (silica, DNA, antibodies, etc.). We also offer PEG-functionalized nanorods, as well as carboxyl-terminated surfaces for bioconjugation.

Citrate is one of our most popular surface options, and is ideal for displacement with other molecules or ligands.

NanoXact materials are high quality, unagglomerated and monodisperse nanoparticles.

Provided at 1 OD or 50 OD in water.

NANOXACT GOLD NANORODS – PEG-CARBOXYL

DESCRIPTION

NanoComposix’s gold nanorods are surface plasmon resonant (SPR) rod-shaped nanoparticles with narrow size distributions and uniform shape. The gold nanorods have absorption peaks that are tunable throughout the visible and short wave near-infrared (SWNIR) regions of the electromagnetic spectrum. Our purification methods remove ammonium surfactants used during synthesis and replace it with citrate, producing a stable, easily displaceable surface chemistry to use as a base for functionalization with a wide variety of molecules (silica, DNA, antibodies, etc.). We also offer PEG-functionalized nanorods, as well as carboxyl-terminated surfaces for bioconjugation.

PEG carboxyl is covalently bound to the metal surface. The acid provides a highly negatively charged surface for subsequent conjugation to proteins, antibodies or peptides.

NanoXact materials are high quality, unagglomerated and monodisperse nanoparticles.

Provided at 50 OD in water.

NANOXACT GOLD NANORODS – PEG

DESCRIPTION

NanoComposix’s gold nanorods are surface plasmon resonant (SPR) rod-shaped nanoparticles with narrow size distributions and uniform shape. The gold nanorods have absorption peaks that are tunable throughout the visible and short wave near-infrared (SWNIR) regions of the electromagnetic spectrum. Our purification methods remove ammonium surfactants used during synthesis and replace it with citrate, producing a stable, easily displaceable surface chemistry to use as a base for functionalization with a wide variety of molecules (silica, DNA, antibodies, etc.). We also offer PEG-functionalized nanorods, as well as carboxyl-terminated surfaces for bioconjugation.

Polyethylene glycol (PEG) is a 5 kDa ligand that is covalently bound to the particle’s surface. The PEG surface provides the highest stability in aqueous buffers and protic solvents..

NanoXact materials are high quality, unagglomerated and monodisperse nanoparticles.

Provided at 50 OD in water.
