Ultra Uniform Gold Nanoparticle Number Standard
Customers outside of the US & Canada: please visit your local distributor’s website to purchase this item using its SKU, or contact us here. Thank you!
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.
Provided at 108 particles/mL in aqueous 1 mM sodium citrate.
Applications
- sp-ICP-MS: Single Particle Inductively Coupled Plasma Mass Spectroscopy
- NTA: Nano Tracking Analysis
- TRPS: Tunable Resistive Pulse Sensing
