Ultra Uniform Gold Nanospheres – PEG-Carboxyl

PEG-carboxyl is covalently bound to the metal surface. The acid provides a highly negatively charged surface and can be utilized for conjugation. Learn more ❯

Ultra Uniform materials are our most highly-monodispersed particles. Ideal for use as size standards or applications requiring a tight size distribution. Learn more ❯

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