Micrographs of bacteria immobilized on a tipless cantilever and a poly-L-lysine-coated glass surface, together with a schematic presentation of the force-distance curves recorded by AFM. (a) Scanning electron micrograph of the tipless cantilever with immobilized actinomyces (upper panel) and light micrograph of a glass surface with an immobilized streptococcal partner (lower panel). The bars used are 5 µm. (b)finally broken and interaction is no longer detected.

Examples of force-distance curves at 10°C, 22°C, and 40°C between A. naeslundii 147 and streptococci, including approach (upper line) and retracting (lower line) curves. (left panel) Co-aggregating pair, involving S. oralis J22. (right panel) Non-co-aggregating pair, involving S. sanguis PK1889.
