Silver Nanoparticles/Nanopowder

Product Properties

Silver (Ag) Nanopowder Main Feature

Silver (Ag) nanopowder, consisting of silver particles at the nanoscale (typically less than 100 nanometers in size), is known for its unique features stemming from its nanoscale dimensions. The main feature of silver nanopowder is its exceptional antimicrobial activity, which surpasses that of bulk silver due to the increased surface area to volume ratio, enhancing its interaction with microbial cells. This makes it highly effective against bacteria, viruses, and other microorganisms.

Additionally, silver nanopowder exhibits:

• High electrical conductivity: At the nanoscale, silver retains its excellent conductivity, making it valuable for electronic applications where small size and high performance are crucial.
• Enhanced optical properties: Silver nanoparticles can interact with light differently than bulk silver, making them useful in photonic devices, sensors, and as colorants in materials.
• Catalytic activity: Silver nanoparticles can act as catalysts in chemical reactions, facilitating processes with efficiency and selectivity.

Silver (Ag) Nanopowder Applications

• Antibacterial Coatings: Utilized in medical devices, textiles, and water purification systems due to its strong antibacterial properties.
• Wound Dressings: Incorporated into bandages and dressings to prevent infections in wounds.Electronics and Conductive Applications
• Conductive Inks and Pastes: Used in printed electronics, RFID tags, and flexible displays for its excellent electrical conductivity.
