Definition

Nano colloidal silver refers to a suspension of nanometer-sized silver particles in a liquid, typically water. These particles range in size from 1 to 100 nanometers and are known for their potent antimicrobial, antibacterial, and antifungal properties. The product is widely used across industries such as healthcare, personal care, food & beverages, textiles, and water treatment.

Due to its strong biocidal activity, nano colloidal silver has found applications in wound dressings, coatings for medical devices, sanitizers, and antimicrobial textiles. It is also explored for use in agricultural and environmental settings. The growing awareness of its efficacy and versatility continues to drive global demand.
