Surface adhesion of Staphylococcus aureus (IMAGE) Saarland University Caption Model of the experimental setup for determining the adhesive force of a bacterium: The corrugated surface allows the lower part of the bacterium (diameter 1 micrometre) to be characterized using single-cell force spectroscopy. The results show that there are a few areas with high adhesive force on the surface of the bacterium.
