[Biophysics seminar] Fabio Staniscia: “Surfactant-induced apparent line tension”
ZoomLine tension is the tension generated at the three-phase contact line by the interaction between the phases, and is usually negligible at large sizes while becoming important at smaller scales. In this talk I will introduce the concept and show … Read More
[Biophysics seminar] Matej Kanduč: “Lipids’ dilemma: a monolayer or a bilayer?”
ZoomLipids are amphiphilic molecules and tend to self-assemble into various supramolecular formations. The most eminent among them is the lipid bilayer - also a continuous barrier around all cells. Some surfaces have the ability to unfold the bilayer and "coat" … Read More
[Biophysics seminar] Tanmoy Sarkar: “A minimal lattice model of lipid membranes with liquid-ordered domains”
ZoomBinary or ternary mixtures of lipids and cholesterol featuring liquid-ordered (Lo) domains serve as model systems for studying the formation of lipid rafts in complex biological membranes. In the talk, I will present a new lattice model of a binary mixture of saturated DPPC … Read More
[Biophysics seminar] Clement Zankoc: “Active Instability and Nonlinear Dynamics of Cell-Cell Junctions”
ZoomActive cell-junction remodeling is important for tissue morphogenesis, yet its underlying physics is not understood. We study a mechanical model that describes junctions as dynamic active force dipoles. Their instability can trigger cell intercalations by a critical collapse. Nonlinearities in … Read More
[Biophysics seminar] Toshikaze Chiba: “Deformation and rearrangement of membranes in adhering vesicles”
ZoomVesicle is a molecular assembly configuring lipid bilayer shell, and investigated as a model system of biological cell. Using both experimental observation and minimising the total energy, we study the morphology of lipid vesicle doublet and triplet. We demonstrate that … Read More

[Biophysics seminar] Urška Andrenšek: “The continuum approximation of the vertex model”
ZoomThe continuum-mechanics approach to the vertex model is useful to understand the phenomenology of tissue deformations during morphogenesis. I will review the past attempzs to derive the continuum theory and compare the theoretical results to the results of numerical simulation. … Read More
[Biophysics seminar] Tomer Stern: “Deconstructing Gastrulation at Single-Cell Resolution”
ZoomGastrulation movements in all animal embryos start with regulated deformations of patterned epithelial sheets. Current studies of gastrulation use a wide range of model organisms and emphasize either large-scale tissue processes or dynamics of individual cells and cell groups. In … Read More
