NanoXact Gold Nanospheres – Bare (Citrate)

Citrate is one of our most popular surface options; the “bare” surface is ideal for displacement with other molecules or ligands. Learn more ❯

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

Provided at .05 mg/mL in 2 mM sodium citrate solution.
