Session III: Active Soft Matter

3929. (I) Hydrodynamic interactions of swimming microorganisms with particles and surfaces

Henry Shum (University of Waterloo)

Symposia Day (DPMB/DCMMP - DPMB/DPMCM) - Soft Matter and Biological and Physics | Matière molle et physique biologique

Invited Speaker / Conférencier(ère) invité(e)

A remarkable diversity of morphologies exists among flagellated bacteria and, more broadly, motile microorganisms. To understand some of the consequences of these design choices, we numerically simulate the swimming motion of flagellated bacteria and model squirmers using a boundary element method. We show that interactions with solid surfaces bounding their fluid environment are particularly...

3626. (I) Embryonic tissues as active matter: modelling developmental processes

Dr Gonca Erdemci-Tandogan (Western University)

Symposia Day (DPMB/DCMMP - DPMB/DPMCM) - Soft Matter and Biological and Physics | Matière molle et physique biologique

Invited Speaker / Conférencier(ère) invité(e)

The material state of embryonic tissues emerges from the collective interactions of cells. Most tissues are soft active materials that can flow or deform. This deformability is shown to be important for proper embryonic development. However, cell and tissue mechanics are experimentally difficult to probe in developing animals. Here, I will discuss our research developing computational and...

3663. (I) Multi-tunable colloids with dipolar and depletion interactions

Symposia Day (DPMB/DCMMP - DPMB/DPMCM) - Soft Matter and Biological and Physics | Matière molle et physique biologique

Invited Speaker / Conférencier(ère) invité(e)

Colloids are mesoscopic particles that enable a systematic study of inter-particle interactions in soft materials. The depletion interaction is an attractive effective interaction that can be tuned by polymer additives, while the amplitude and frequency of an external electric field can be used to tune the dipolar interaction. Using these two interactions simultaneously, we create...
