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].
