Darwin microfluidics shear stress
WebMar 14, 2024 · In microfluidic conditions, we observe that cell scavenging generates spatial gradients of H 2 O 2. High shear rates replenish H 2 O 2, abolish gradients, and generate a stress response. Combining mathematical simulations and biophysical experiments, we find that flow triggers an effect like "wind-chill" that sensitizes cells to H 2 O 2 ... WebFreestanding lipid bilayers are formed in microfluidic devices following a previously described protocol (38, 39) (Materials and Methods). ... We now characterize the transmission of shear stress from one side of the bilayer to the other and therefore, the interlayer interactions between the two leaflets of the bilayer. ...
