Produced in our state-of-the-art facilities and offered at competitive prices, it provides the reliability researchers, diagnostic developers, and high-tech manufacturers demand—delivering consistent results from proof-of-concept through full-scale production.
What is Colloidal Silver?
Colloidal silver is a stable suspension of metallic silver nanoparticles (typically 5–100 nm) in an aqueous medium. Its pale-yellow to amber hue arises from size-dependent surface-plasmon resonance (SPR), while controlled Ag⁺ ion release underpins its broad-spectrum antimicrobial activity. Key attributes include:
- Potent antibacterial, antiviral, and antifungal efficacy at low concentrations
- Excellent electrical conductivity for printed electronics and conductive inks
- Ease of surface functionalisation (thiols, amines, carboxyls, antibodies, DNA, polymers)
- High catalytic activity in redox and reduction reactions
- Long-term colloidal stability with minimal aggregation
- Size tunability to match diverse research and industrial requirements
Applications of Colloidal Silver
Ready-to-use aqueous dispersions enable a wide range of solutions:
- Wound-care dressings and antimicrobial textiles
- SERS and other plasmonic biosensors
- Rapid lateral-flow diagnostics and test strips
- Conductive inks, RFID antennas, and low-temperature sintered circuits
- Water-purification membranes with biofilm resistance
- Catalysts for selective reduction and oxidation processes
- Cosmetic formulations and polymer/composite additives
