Abstract
Natural (cotton) and synthetic (polyester) fabrics functionalized with the SilverSil xerogel powder dispersed in water-repellent. ecofriendly commercial textile finishings acquire substantial antibacterial activity against both Gram-positive and Gram-negative bacteria. Here demonstrated against Staphylococcus aureus and Escherichia coli bacteria, said activity is due to the Ag nanoparticles sol-gel entrapped within the organically modified silica matrix. Ease of deposition using a printing method, low application rate, and enhanced physical and chemical stability of the ORMOSIL-entrapped Ag nanoparticles are promising towards the production of the first durable antimicrobial fabrics and garments, minimizing antimicrobial resistance.
