❮ BioPure: Purified & Sterile

BioPure Silver Nanospheres – Bare (Citrate)·

Citrate is one of our most popular surface options; the “bare” surface is ideal for displacement with other molecules or ligands. 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 75 nm BioPure Silver Citrate and 10 and 75 nm BioPure Silver PVP can be used as OECD standards for nanotoxicology testing.

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