Study of the effect of mechanical stiffness substrata, assembled with polyelectrolyte multilayer thin films, on biofilm forming staphylococcus epidermidis' initial adhesion mechanism
… of infections acquired in hospitals. Currently mechanisms responsible for the initial adhesion of bacteria are not completely understood. Previous work completed in the Rubner and Van Vliet labs at MIT suggests a mechanoselective adhesion mechanism in prokaryotes. The existence of a positive …

Biologically inspired underwater propulsion and adhesion mechanisms
… thesis include two different parts: a propulsion mechanism using a passive compliant tail and a reversible underwater adhesion mechanism. The propulsion mechanism is the primary concern of this research. The hypothesis of this part of research is that a continuous passive compliant tail structure …
