• resistant against washing out in procedures. It has recently been shown that the deposition of metal NPs using the cluster beam technique is an efficient approach in the formation of polymer composite films with antibacterial properties. The composites can be formed by either incorporation of particles

• [9][10][11][12][13][14][15]. In the current work, both Ti and Cu clusters are produced using magnetron sputtering in special cluster sources and deposited on substrates coated by a thin layer of polystyrene (PS). The focus is on the optimization of the nanocomposite formation using the cluster beam
