Silver (Ag) Nanopowder/Nanoparticles Water Dispersion 

Purity: %99.99, Size: 3 nm, 2200 ppm

Silver (Ag) Nanoparticle Water Dispersion (Colloidal Silver) is a premium, ultra-high concentration research-grade solution featuring an extraordinary particle size of just 3 nm, engineered for applications where maximum silver efficacy is required. This ultra-fine scale provides an immense surface-area-to-volume ratio, significantly amplifying the material's reactive and antimicrobial potency while maintaining a remarkable colorless and transparent physical state. As a specialized research-grade formulation, this light-sensitive dispersion is designed for professional use, ensuring high colloidal stability and seamless integration into aqueous systems through simple mixing. Its neutral pH and lack of discoloration make it an ideal "drop-in" additive for sophisticated nanotechnology studies and high-end industrial processes, provided it is handled with the precision required for advanced nanomaterials and stored away from direct sunlight to preserve its integrity.

Technical Properties

Applications

• High-Performance Biomedical and Healthcare: Due to the 3 nm particle size, this dispersion exhibits superior cell-penetrating capabilities and enhanced silver ion release, making it exceptionally effective for advanced medical research. It is used in the development of high-potency antimicrobial gels, wound healing accelerators, and sterile coatings for surgical instruments. Its high concentration allows for the creation of powerful antiseptic formulations even after significant dilution.
• Textile and Smart Fabric Engineering: This dispersion is utilized for the high-durability antibacterial finishing of premium textiles, including technical fabrics and luxury leather. The ultra-small nanoparticles embed more deeply into fiber structures than larger particles, providing superior wash-fastness and long-lasting protection against bacteria and fungi. It is ideal for performance wear where maintaining hygiene and preventing odor are critical.
• Advanced Polymer and Paint Additives: In the coatings industry, the 2200 ppm concentration makes this product an efficient masterbatch additive for anti-biofouling paints and architectural coatings. It provides a robust defense against microbial degradation and mold growth. Because it is colorless and transparent, it can be integrated into high-gloss or clear coatings without affecting the optical clarity or the intended pigment profile.
• Sanitization and Deodorizing Agents: The product serves as a potent active ingredient in professional-grade deodorants and sanitizers for personal belongings, electronics, and footwear. Its high efficacy at low concentrations makes it an economical yet powerful solution for eliminating odor-causing microorganisms at their source, ensuring long-term freshness in consumer products.
• Nanosensor and Diagnostic Research: In molecular biology and genetic diagnostics, the 3 nm silver particles are vital for enhancing detection sensitivity in biosensors. Their unique plasmonic properties are explored in Surface-Enhanced Raman Scattering (SERS) and other advanced imaging techniques, where the high purity and uniform dispersion are essential for reproducible scientific data.
• Specialized Paper and Packaging: The dispersion is applied to high-end specialty papers and food-contact packaging to prevent cross-contamination and extend shelf life. Its easy-to-dilute nature allows for precise application in industrial spraying or dipping processes, imparting strong antimicrobial barriers to paper-based medical supplies and sensitive packaging materials.
