NanoXact Gold Nanorods – PEG·

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

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. Learn more ❯

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