• "Bare" citrate surface is stable and displaceable

Spherical silver nanoparticles, 1 mg/ml (high concentration). Citrate offers stable and readily displaceable surface. BioPure materials are Sterile and Endotoxin to Free (<5 EU/ml). Precisely engineered, unagglomerated nanospheres with narrow size distributions (CVs <15% for 30 to 200 nm sizes, <20% for 20 nm, and <25% for 5 and 10 nm sizes).

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 silver has applications in Diagnostics, Antimicrobial coatings, Electronics and Photovoltaics, SERS, Optics, Nanotoxicology, Plasmonics (SPR / Surface Plasmon Resonance), novel Color Enhancements and Pigments, Molecular Detection, Sensors, and Photothermal and Microwave-based Therapies.

Custom formulations and ISO13485/cGMP compliant materials can be provided on request.
