Abstract. The general context of this work is to study the effect of physicochemical and morphological properties on bacterial adhesion. In this case, the adhesion of Staphylococcus aureus (gram positive bacteria) has been studied in thin films of zinc oxide (ZnO). The contact angle measurements were used to calculate the surface energy components of each substrate and analysis of adherent cells on the surface was made by the atomic force microscopy. The results showed that the glass surface is governed by short range forces (Lewis acid–bases forces) and that ZnO film is governed by long range forces (van der Waals forces). Images obtained by atomic force microscopy revealed that the ZnO layer has an antibacterial effect against S. aureus.
