Silver (Ag) Nanopowder/Nanoparticles Water Dispersion 

Purity: 99.99%, Size: 14 nm, 1200 ppm 

Silver (Ag) Nanoparticle Dispersion is a high-purity, chemically reduced colloidal system featuring 14 nm nanoparticles at a robust concentration of 1200 ppm. Characterized by its distinctive yellowish-brown hue—a natural optical result of the Surface Plasmon Resonance (SPR) at this specific particle size—this dispersion offers a stable and potent medium for professional research and industrial integration. With a neutral pH and a controlled Zeta Potential ranging from -17 mV to -38 mV, the solution ensures excellent particle stability and resistance against premature agglomeration. As a high-performance research-grade material, it is designed for ease of use via simple dilution and mixing; however, it remains light-sensitive and must be stored away from direct sunlight and handled by professionals to maintain its optimized colloidal integrity over time.

Applications

• Antimicrobial Surface Engineering: Leveraging the high efficacy of 14 nm silver particles, this dispersion is extensively used to impart antimicrobial properties to various surfaces. It is ideal for the antibacterial finishing of textiles, including high-quality leather, and paper products. The nanoparticles create a long-lasting barrier against pathogenic microorganisms, making it a key component in developing self-sanitizing materials for public and clinical environments.
• Advanced Medical and Skin-Care Formulations: The dispersion’s purity and chemical stability make it a preferred additive for medical-grade skin products, such as antibacterial gels, lotions, and specialized wound-care treatments. Its well-defined particle size ensures consistent silver ion release, providing reliable localized protection against bacterial growth while maintaining biocompatibility in topical applications.
• Deodorizing and Sanitizing Agents: This colloidal silver is highly effective in neutralizing odor-causing bacteria. It is integrated into professional-grade deodorants for personal belongings, including footwear, toys, and sports equipment. Its concentrated format allows for significant dilution while remaining potent enough to eliminate microbial activity in household and industrial sanitization products.
• Functional Paints and Coatings: When added to paints and architectural coatings, the Ag dispersion acts as a powerful deodorizing and anti-mold agent. It protects interior and exterior surfaces from biofilm formation and environmental degradation. The chemically reduced stability of the particles ensures they remain active within the coating matrix, providing durable protection for infrastructure.
• Biotechnology and Nanomedicine Research: As a research-grade product with a verified Zeta Potential, this dispersion serves as a critical tool in studying nanoparticle-cell interactions, drug delivery systems, and biosensor development. The 14 nm size is particularly valuable for experiments involving surface-enhanced optical phenomena and the investigation of silver's synergistic effects with other bioactive compounds.
• Environmental and Industrial Filtration: The dispersion is explored in the development of advanced water and air filtration membranes. By coating filter media with silver nanoparticles, manufacturers can create bioactive filters that not only trap particles but also neutralize bacteria and viruses trapped on the surface, preventing the buildup of organic contaminants.
