Ultra Uniform Gold Nanoparticle Number Standard
Ultra Uniform materials are our most highly-monodispersed particles. Ideal for use as size standards or applications requiring a tight size distribution. Our Ultra Uniform Particle Number Standards provide additional characterization and careful formulation for applications that require a known particle number concentration. Learn more ❯
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 ❯
