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.

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.

NanoXact materials are high quality, unagglomerated and monodisperse nanoparticles.

Provided at .05 mg/mL or 1 mg/mL in water.

Nanoparticle powder, specifically formulated to maintain the nanoparticles’ unique properties – no aggregation! Powder format allows greater flexibility with solvent choice and concentration.

Polyvinylpyrrolidone (PVP) helps maintain stability when particles are deposited onto a substrate or thin film.
