NanoXact Silver Shelled Gold – Bare (Citrate)
Bimetallic core-shell nanoparticles with tunable core diameter and shell thickness are unique nanomaterials with controllable optical properties and atomic ratios, of interest for plasmonic studies and as highly-characterized constructs for single particle elemental analysis.

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 1 mg/mL (total gold and silver content) in aqueous 2 mM citrate.
