BioPure Silver Nanospheres – PVP

Polyvinylpyrrolidone (PVP) is a large polymer that is securely attached to the surface and offers excellent steric stability. Great choice for withstanding a broad range of salt, pH, and solvent conditions. Learn more ❯

BioPure materials are high quality, unagglomerated, and monodisperse nanoparticles. Extensively purified and provided sterile with low endotoxin. Ideal for in-vivo and in-vitro studies and medical applications. Learn more ❯

Additionally, our 10 and 75 nm BioPure Silver PVP and 75 nm BioPure Silver Citrate can be used as OECD standards for nanotoxicology testing.

Provided at 1 mg/mL in water.

We recommend using ≤ 30 nm sizes of PVP silver within 30 days of receipt. Click here for more info.
