NanoXact Gold Nanoshells – PVP

Gold nanoshells consist of a silica core surrounded by a gold shell. By changing the ratio of the size of the core to the thickness of the shell, the plasmon resonance can be tuned across the visible and infrared. Learn more ❯

Polyvinylpyrrolidone (PVP) is a large polymer that offers excellent steric stability. Great choice for particles that may be exposed to a broad range of salt, pH, and solvent conditions. Learn more ❯

NanoXact materials are high quality, unagglomerated and monodisperse nanoparticles. Learn more ❯

Provided at 0.05 mg/mL or 1 mg/mL in water.
