Abstract
In biological adhesion systems, a wide range of cell contact geometries has been found.1–3 Where cells such as pollen or fungal spores need to be dispersed, the surfaces tend to be covered by spikes which prevent intimate extended contact between the particles, allowing the van der Waals force to be reduced to a low value. When adhesion needs to be maximised, for example where flies cling to the ceiling or lizards run up walls, the surfaces tend to split into close-packed hairy fibres or setai ending in flattened spatula tips.
