Ultrasound irradiation was used for anchoring silver nanoparticles with an average size from 10 to 50 nm onto the surface of acrylonitrile–butadiene–styrene (ABS) sheets 1 mm thick. The sonochemical reduction was carried out under argon at room temperature. Silver nanoparticles were obtained and deposited on the ABS surface by the irradiation of a mixture containing ABS sheet, silver nitrate (AgNO 3 ), ethylene glycol and water. Reaction conditions such as temperature, AgNO 3 concentration and irradiation time were controlled to achieve the deposition of silver nanoparticles onto the surface of Abs antibacterial sheet. Nano silver coated ABS samples were characterized by X-ray diffraction, transmission and scanning electron microscopy, Raman spectroscopy and antimicrobial activity,
