Biocidal Applications of Silver Substances
Silver has been used as an antimicrobial agent since ancient times.
Early cultures such as the Persians, Greeks, and Romans used silver containers and utensils to preserve water and support wound healing. Over time, silver’s use expanded from treating infections and preserving liquids in the 1800s to its current applications in healthcare, water treatment, textiles, and food safety.
Today, silver-based substances are widely used to prevent microbial growth and support public health.
Key applications include
Use as a Disinfectant
Silver is included in a variety of disinfectant products for both healthcare and domestic settings. It enhances the efficacy of surface cleaners, wound dressings, and antiseptic sprays by providing long-lasting antimicrobial protection.
Material Preservation
Silver compounds are added to polymers, coatings, and construction materials to inhibit the growth of bacteria, mold, and algae. This helps maintain the integrity and appearance of building materials, paints, and consumer products.
Food Safety
Silver acts as a biocide on food contact surfaces and polymer-based storage products. Common uses include treatment of storage containers, sealing rings in packaging, and refrigerator linings to reduce microbial contamination and extend shelf life.
Textiles
Silver ions embedded in fabrics inhibit bacteria, mold, and fungi. This antimicrobial property helps reduce odors and extends fabric usability by maintaining effectiveness after multiple washes. Silver is applied to various fibers including cotton, polyester, nylon, and wool. Typical applications include professional clothing (healthcare, food processing), sportswear, underwear, and technical textiles.
Water Treatment
Silver, often combined with copper, is used in water treatment to control microorganisms such as Legionella and E. coli. These systems are applied in hospitals, hotels, and large buildings where water distribution networks require microbial control.
