The sonochemical technique has been already proven as one of the best coating methods for stable functionalization of substrates in a broad range of applications. Here, we report for the first time on the simultaneous sonochemical dyeing and coating with antibacterial metal oxide (MO) nanoparticles of textiles. In this one-step process the antibacterial nanoparticles are synthesized in-situ and deposited together with dye nanoparticles on the fabric surface. It was shown that the antibacterial behavior of the metal oxides was not influenced by the presence of the dyes. Higher K/S values were achieved by sonochemical deposition of the dyes in comparison to a dip-coating (exhaustion) process. The stability of the antibacterial properties and the dye fastness was studied for 72 hours in saline solution aiming at medical applications
