2.2.3 Surface mechanical sensing
Surface mechanosensing, on the other hand, is the ability of bacteria to sense physical contact with the substrate through mechanics[33]. Mechanosensing triggers a signaling shift from a planktonic mode to a biofilm growth mode[32]. Studies have shown that bacteria inhibit the rotation of pili and bacterial bodies by ”sensing”[12], providing the potential for attachment to the surface of the material and that the interaction between their sensing organs, coats, and flagella, allows for the rapid and timely production of adhesins, thus facilitating the transition from reversible to irreversible attachment [35]. In surface mechanosensing, bacteria can actively sense when they touch a surface, and because it may involve a series of biological reactions, this effect takes longer than the first two interactions.[12].
