Nanosilver Migrates from Treated Fabric During Washing Silver nanoparticles used as antimicrobials in fabric can leach out of clothes as they are being washed. One brand lost over half of its silver content from the fabric with just two washings. A group of scientists tested how well silver nanoparticles stayed in treated fabrics under conditions similar to a washing machine. They considered mechanical stress and chemical factors such as bleaches, pH and surfactants. First, they measured the silver content of several different brands and types of fabrics that used silver nanoparticles. They then washed the [...]
