NanoComposix’s dried silver nanopowders are formulated with polymer or alkanethiol surface coatings which allow the nanoparticles to easily be redispersed as unagglomerated dispersions in a variety of solvents. We have verified the redispersion with transmission electron microscopy (TEM), UV-visible spectroscopy and dynamic light scattering. Please contact us if you would like other sizes.
N NanoXact, 0.02 mg/mL. Narrow size distribution, wide variety of surfaces.
D NanoXact, dried. Available only with PVP.
B BioPure, 1 mg/mL. Purified and concentrated NanoXact. Sterile and endotoxin-free. (Not available dried.)
E Econix, 5 mg/mL. Larger quantities, lower cost.
D Econix, dried. Available only with PVP.
