Interstitial flow potentiates TGF-/Smad-signaling activity in lung cancer spheroids in a 3D-microfluidic chip
Zaid Rahman, Ankur Deep Bordoloi, Haifa Rouhana +4
Within the tumor microenvironment (TME), cancer cells use mechanotransduction pathways to convert biophysical forces to biochemical signals. However, the underlying mechanisms and…
Tuning local microstructure of colloidal gels by ultrasound-activated deformable inclusions
Brice Saint-Michel, George Petekidis, Valeria Garbin
Colloidal gels possess a memory of previous shear events, both steady and oscillatory. This memory, embedded in the microstructure, affects the mechanical response of the gel, and…
Enhancing microalgal cell wall permeability by microbubble streaming flow
Angelo Pommella, Irina Harun, Klaus Hellgardt +1
We demonstrate that the permeability of the cell wall of microalga can be enhanced in controlled microstreaming flow conditions using single bubbles adher…
Bubble dynamics for broadband microrheology of complex fluids
Brice Saint-Michel, Valeria Garbin
Bubbles in complex fluids are often desirable, and sometimes simply inevitable, in the processing of formulated products. Bubbles can rise by buoyancy, grow or dissolve by mass tra…
Acoustic Bubble Dynamics in a Yield-Stress Fluids
Brice Saint-Michel, Valeria Garbin
Yield-stress fluids naturally trap small bubbles when their buoyancy applies an insufficient stress to induce local yielding of the material. Under acoustic excitation, trapped bub…
Oscillations of small bubbles and medium yielding in elastoviscoplastic fluids
Marco De Corato, Brice Saint-Michel, George Makrigiorgios +3
We investigate the radial oscillations of small gas bubbles trapped in yield-stress fluid and driven by an acoustic pressure field. We model the rheological behavior of the yield-s…
Dynamic capillary assembly of colloids at interfaces with 10,000g accelerations
Axel Huerre, Marco De Corato, Valeria Garbin
Extreme deformation of soft matter is central to our understanding of the effects of shock, fracture, and phase change in a variety of systems. Yet, despite, the increasing interes…
Hydrodynamic mobility of confined polymeric particles, vesicles and cancer cells in a square microchannel
Shamim M. Ahmmed, Naureen S. Suteria, Valeria Garbin +1
The transport of deformable objects including polymer particles, vesicles and cells, has been a subject of interest for several decades where the majority of experimental and theor…
High-frequency capillary waves excited by oscillating microbubbles
Angelo Pommella, Jeanne Lantz, Vincent Poulichet +1
This fluid dynamics video shows high-frequency capillary waves excited by the volumetric oscillations of microbubbles near a free surface. The frequency of the capillary waves is c…
