BioPure Magnetite Nanoparticles – PVP

Our magnetite nanoparticles are 20 nm colloidal iron oxide (Fe₃O₄) materials that exhibit superparamagnetic properties at ambient temperatures. Learn more ❯

Polyvinylpyrrolidone (PVP) is a large polymer that offers excellent steric stability. 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 ❯

Provided at 1 mg/mL in aqueous 2 mM sodium citrate.
