IPPG Connection presents
MEETUP ABOUT MICROFLUIDIC & MORE
Every Third Wednesday of each month, 11 AM - noon.
6, rue Jean Calvin
75 005 PARIS.
As before, this meeting will be focused on the physics underlying biological interactions at microscale. Microscale technologies are emerging as powerful tools for tissue engineering and biological studies. The use of microfluidics, surface patterning, and patterned co-cultures in regulating various aspects of molecular and cellular microenvironment has been increasingly sought to. In “Microscale Affairs”, we aim to discuss these tools, related techniques and their applications.
11.00 AM - NOON
Main speaker :
Pole Microfluidique - ENS Paris
“Magie molle” - Soft wizardry: DNA nanomachines, metafluidics and living crystals :
Many common biological and synthetic systems (DNA, proteins, membranes, colloids, fluids, drops), despite their apparent diversity, share a “soft” character that, in our group, we like to study, exploit or stimulate, either to perform useful processes in a novel and simpler way or to study curious/puzzling phenomena. In this talk, I will show that this approach allows us to provide materials with unique properties, such as reconfigurability and stimulus-responsivity, or to achieve useful operations like autonomous microfluidics and low-cost diagnostics.
I will first show that using DNA as a soft material allows us to build functional artificial cell systems, optically control gene expression or create soft reconfigurable DNA nanomachines. I will then describes our efforts to identify new actuation principles to make microfluidics better, easier and cheaper, showing how light from simple LEDs, or weak magnetic fields from cost-effective magnets, can be used to control a broad variety of fluidic operations, ranging from drop and liquid marble transport to flow control and dynamic mixing.
I will also present new ways to harness the so-called “coffee-ring effect” allowing us to convert this familiar phenomenon into a powerful tool, with applications ranging from ubiquitous particle patterning to low-cost medical diagnostics. I will finally describe a novel and strikingly simple way to prepare mm-sized 2D colloidal crystals at the air-water interface, render them photo-responsive and observe some interesting properties such as structural colouration or surprising dissipative characteristics.
