Purified, concentrated, high quality gold nps, sterile and endotoxin-free. PVP for stability.

• High quality nanoparticles, precisely engineered and highly characterized
• Unagglomerated and monodisperse
• High concentration materials (1 mg/ml, 5.08 mm, 1000 ppm)
• Extensively purified to remove residual reactants
• Manufactured sterile; provided in ultra to pure (Milli to Q) DI water
• BioPure mateirals ideal for in to vitro and in to vivo experiments, nanotoxicology
• PVP surface provides strong steric stability

Spherical gold nanoparticles, 1 mg/ml (high concentration), PVP polymer surface provides strong steric stability (40 kD polyvinylpyrrolidone). BioPure materials are Sterile and Endotoxin to Free (<5 EU/ml). Precisely engineered, unagglomerated nanospheres with narrow size distributions (CVs <12% for 7 to 15 nm sizes, <15% for 20 to 100 nm sizes, and <18% for 5 nm size).

Each batch is extensively characterized to meet highest quality standards, ensuring reliable and reproducible results. All products supplied with COA's including batch-specific TEM, DLS, Zeta, UV-Vis measurements, etc.

Colloidal gold has applications in Diagnostics, Lateral Flow Assays, Molecular Detection, Photothermal and Microwave-based Therapies, TEM labels, Nanotoxicology, Plasmonics (SPR / Surface Plasmon Resonance), and novel Color Enhancements and Pigments.
