NanoXact Gold Nanorods – Bare (Citrate)

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

Citrate is one of our most popular surface options, and is ideal for displacement with other molecules or ligands. Provided CTAB-free! Learn more here.

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

Provided at 1 OD or 50 OD in water.
