The Surface Forces Apparatus (SFA) is a force spectroscopic technique to directly measure the interaction forces between two macroscopic surfaces, with sub-nanometer distance resolution and tens of piconewton force sensitivity. Combined with multiple beam interferometry (MIB), we can observe the boundary between a solid and biomolecule film in real-time and in situ. This seminar will describe the SFA, and how we are using it to elucidate the molecular mechanisms that allow bacteria stick to surfaces in aqueous and salt-rich environments to engineer wet adhesives with potential use in biomedical applications, as well as the molecular interactions that regulate friction and wear in synovial joints, such as the knee or hip.

Hosted by professors Alex Boys and Emily Asenath-Smith.
