• properties and the dye fastness was studied for 72 h in saline solution aiming at medical applications. Keywords: antibacterial nanoparticles; coating stability; dyes; sonochemical coating; Introduction The preferred technique for coating with nanoparticles (NPs) in most scientific and industrial examples

• maintained constant during the sonochemical coating reaction by cooling the flask with cold water. The coated fabric was first washed thoroughly with water to remove traces of ammonia, then with ethanol, and dried under vacuum. A control experiment, in which only the dye (RO16 or RB5) was deposited

• undergo chemical changes. A control dyeing was carried out by dip-coating the fabrics in an alkaline (ammonia) dye solution for 60 min, the same time as the sonochemical coating reaction. Higher K/S values were obtained for the sonochemically ZnO-coated samples as compared to the regular dip-coated
