Silver (Ag) Nanopowder/Nanoparticles Water Dispersion

2.200 ppm Size: 2-5 nm, Colorless & Transparent, 1000±5ppm

Silver (Ag) Nanoparticles Water Dispersion is an ultra-high performance colloidal system featuring exceptionally small silver particles (2-5 nm) optimized for maximum biological and chemical reactivity. Due to the quantum-scale dimensions of the particles, this dispersion provides a massive surface-area-to-volume ratio, allowing for high efficacy at significantly lower concentrations than standard silver solutions. Despite its robust 2200 ppm total dispersion content, the product is meticulously engineered to remain colorless and transparent, ensuring it imparts powerful antimicrobial and conductive functionalities without altering the aesthetic or optical properties of the host material. This research-grade, aqueous dispersion is designed for professional environments where high stability, neutral pH compatibility, and long-term suspension are critical, offering a versatile and easy-to-integrate solution for advanced nanotechnology applications.

Technical Properties

Applications

• High-Precision Textiles and Specialty Fibers: This dispersion is used to impart permanent antimicrobial properties to cotton, blended fabrics, and synthetic fibers without causing discoloration. Because of the 2-5 nm particle size, the silver penetrates deeper into the textile matrix, providing superior resistance to laundering while preventing the growth of odor-causing bacteria and fungi in performance sportswear and medical textiles.
• Advanced Cosmetics and Personal Care: Integrated as a high-purity antimicrobial additive, this dispersion is ideal for premium lotions, gels, and soaps. Its transparent nature allows for the formulation of clear cosmetic products that remain safe from microbial contamination throughout their shelf life. The ultra-fine particles ensure a smooth, non-gritty texture and enhanced skin compatibility in dermatological applications.
• Optically Clear Coatings and Paints: Silver (Ag) water dispersion is a key additive for water-based coatings that require long-lasting antibacterial protection without affecting transparency. It is particularly valued for high-gloss finishes, clear wood lacquers, and architectural coatings where maintaining the original color and clarity of the substrate is paramount.
• Medical Hygiene and Disinfectants: Leveraging its broad-spectrum activity against pathogens like E. coli and S. aureus, this dispersion is used in the manufacturing of medical-grade antibacterial sprays and sanitizers. The small particle size allows for rapid ion release, providing faster and more efficient disinfection in hospital environments and for sterile medical equipment surfaces.
• Innovative Food Packaging and Preservation: When integrated into packaging films and plastics, the nanoparticles inhibit the growth of mold and bacteria on the surface of the packaging. This helps extend the freshness of food products and prevents cross-contamination, making it a vital component in modern active packaging solutions.
• Nanosensing and Water Purification: In scientific research, the 2-5 nm size is explored for advanced biosensing and water treatment systems. The high surface reactivity helps in reducing the bacterial load in aqueous environments and enhances detection sensitivity in diagnostic tools, providing a reliable platform for environmental monitoring and molecular research.
