Seminars

The MRSEC holds seminars presenting research at the frontier of Bioinspired Soft Materials. The seminars are targeted towards grad students and other researchers in the field, although everyone is invited to attend. As the topic is highly interdisciplinary, seminars are designed to be accessible to a wide range of backgrounds. 

The seminars take place in Abelson 229 at 4PM.

MRSEC Seminar: Chiral, Active & DNA-functionalized Colloids
Samia Ouhajji, Leiden University, Postdoctoral Fellow
Abstract: In this seminar I will present three colloidal model systems. I will start by showing two preparation methods to synthesize chiral colloids from isotropic spheres. The first method relies on the confinement of colloidal spheres in hollow microtubes. Depending on the colloid-to-tube diameter ratio, various structures can be formed in bulk. The second preparation route for chiral colloids combines dipolar hard spheres and depletion interaction. When a magnetic field is applied in the presence of depletion polymer, linear sphere chains wind around each other transforming into helical structures.
In the second part of this talk, I will discuss (artificial) taxis, the ability of bacteria and living cells to adapt their motion in response to external stimuli. Recently Liebchen et al. found that swimmers with nonuniaxial body shapes swim up viscosity gradients due to the generation of asymmetric viscous torques acting on different parts of the swimmer.. We are testing these theoretical predictions using artificial microswimmers created by 3D printing.
Finally, I will demonstrate how we aim to synthesize flexible colloidal molecules with a constrained range of motion using phase-separated colloid supported lipid bilayers and mobile DNA linkers.
