Bacterial biofouling is a huge problem within food production industries (food processing surfaces, processing equipments). The adhesion of bacteria to a surface is given by a combination of factors such as chemical composition, surface topography, mechanical properties and environmental conditions. Among them, surface topography is the most important parameter to trigger cell adhesion. Therefore, one method to prevent bacterial biofouling would be to modify the topographical structure of the surface. There are different opinions on how surface characteristics affect bacterial adhesion. Some reports have shown a positive correlation between adhesion and increased surface roughness while others reported no correlation at all.In this study, we investigate how micro/nano-scale topographies impact bacterial surface attachment.
