Figure 2: Membrane deformations induced by actin assembly. A membrane bilayer (pink) constituting an initially spherical liposome is deformed through the growth of a branched actin network (blue marks the colour of the end of actin filaments) at its surface. Spikes (inward) and tubes (outward) are formed during this process. Note that compared to the cell geometry, the geometry here is inside out, as the ingredients of the cytoskeleton are outside the liposome. Bar 5 μm. Copyright: Cécile Sykes, CNRS

How Active Biopolymer Networks Shape the Cell Membrane

Experiments on active deformations of a cell membrane by an actin assembly may inspire new materials and approaches. Cécile Sykes from the Laboratoire de Physique de l‘Ecole Normale Supérieure reports on results raising... (Read more)

Creep Dynamics and Failure of a Biopolymer Gel

Failure is a topic that has received a lot of attention in the community of soft matter from a scientific and industrial point of view. Among soft systems, understanding failure in biopolymer gels... (Read more)
