[BIC-announce] Seminar in Biomedical Engineering - Wednesday May 7th - 1h pm - Room 333

[Christophe Grova]

Dear all,

We will have our next  Biomedical Engineering seminar this coming Wednesday

Wednesday  –  May 7th,  at 1 pm

Location: Room  333 Lyman Duff Building (Biomedical Engineering Dpt, 3775  University Street).

Speaker:  Prof. Allen Ehrlicher PhD, Department of Bioengineering, McGill University

Dr. Ehrlicher is candidate for associate membership in Biomedical Engineering department,
so attendance from our staff members and their students is highly encouraged.


Title:
"Force Spectrum Microscopy Reveals Active Diffusive-like Behavior in
Living Cells"


Abstract:

Passive soft materials, even complex ones, display mechanics which can
be largely understood in terms of temperature. It is tempting to apply
these concepts to biology, however, biological systems are far from
equilibrium. Indeed, biological systems are unique among materials in
that they not only produce active forces, but they also dynamically
change their mechanical properties; both of these are essential aspects
of animal life, and they function together to create surprising
properties.  In this talk, I will discuss how active processes can
produce random "diffusive-like" transport in the cytoplasm of living
cells. Using a combination of particle tracking and active
microrheology, we quantitatively determine the contribution of active
ATP driven-processes, and show that these dominate random transport
activity on time-scales greater than about 1 second.  This methodology
also provides the first measurements of the complete internal
force-spectrum in living cells.
