NanoXact Platinum Nanoparticles – 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. 5, 30, and 50 nm sizes supplied in aqueous 2 mM sodium citrate; 70 nm size is in aqueous 4 mM sodium citrate.
