30 years later: the dynamical transition studied under high hydrostatic pressure

Proteins are not fixed, they constantly change their conformation due to fluctuations in their energy landscape. Beyond a certain temperature, these dynamic changes of conformation are important, proteins undergo what is called a dynamic transition. This work examines the effect of pressure on this transition observed originally 30 years ago.

Are cells ticklish?

Cells are sensitive to their mechanical environment: pressure or shear can provoke biochemical responses. In order to accurately test the reaction of adherent cells to mechanical stimulations, we developed magneto-active substrates.

Exclusion zones created by pulsating bubbles in microfluidics

Under ultrasonic excitation, microfluidic bubbles can create steady flows called streaming. This phenomenon can be useful to create very strong flows in microfluidics, as streaming velocities can reach up to a few millimetres per second for bubbles sizing around 50 microns in diameter.

Hollow sphere swims like a jellyfish thanks to sound waves.

Powering microrobots inside a human organism would be useful for delivering small quantities of drugs at the right place, thus increasing their efficiency and reducing the possible side effects.
