NanoXact Gold Nanorods – PEG-Carboxyl

Gold nanorods have absorption peaks that are tunable throughout the visible and short wave near-infrared (SWNIR) regions of the electromagnetic spectrum. Learn more ❯

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. Learn more ❯

NanoXact materials are high quality, unagglomerated and monodisperse nanoparticles. Learn more ❯

Provided at 50 OD in water.
