• (i.e., the marking of cell movement by the voids created on a nanoparticle carpet) was used already in 1977 to visualize cell migration [15]. Because nanoparticles are so prevalently used to coat surfaces (for instance, to create biofilm resistance on implants [16], to enhance stability or to create a

• pressure difference at vacuum conditions can be ameliorated under water, due to the increasing pressure with water depth. Keywords: adhesion; biofilm; friction; hooks; suction; Introduction Attachment in animals, plants and microorganisms serves a variety of functions: the interconnection of body parts

• considered for aquatic systems. While most terrestrial animals make contact directly with the substrate, in aquatic environments the substrates are usually covered with a biofilm and fouling organisms (Figure 3). Biofilms play not only an important role in stimulating or inhibiting the settlement of fouling

• , and fluid properties, implies they will be useful. A further complication in water bears mention: The biofilm of fouled surfaces has a high effective viscosity and is also viscoelastic [26]. It is likely that an empirical understanding of viscous adhesion of animals to biofilms will have to be
