Phase coexistence and nucleation of aging condensates
Yicheng Qiang, Chengjie Luo, David Zwicker
Biomolecular condensates form by phase separation and often age over time by transitioning from liquid-like droplets to solid-like states. To capture the fundamental behavior of ag…
Fluctuating chemically active droplets
Guido L. A. Kusters, Noah Ziethen, Michael E. Cates +1
We study size fluctuations of chemically active droplets in the regime of weak reactions and strong phase separation. By combining a thin-interface model for the deterministic drop…
Speed up of passive tracers in mixtures with active chemical reactions
Filipe C. Thewes, Chengjie Luo, David Zwicker
Diffusivity of passive tracers in complex mixtures is widely relevant for industrial applications and for probing biological systems. Interactions with the surrounding medium typic…
Phase diagram morphology shapes droplet propulsion in chemical gradients
Stefan Köstler, Malcolm Steen, David Zwicker
Droplets in complex environments often encounter compositional gradients that drive their propulsion. For example, surfactant gradients induce surface-tension-driven propulsion via…
Oscillating concentrations suppress condensate coarsening
Mathias S. Heltberg, Lukas H. Kristensen, Mogens H. Jensen +1
Living cells utilize condensates to spatially concentrate molecules in response to dynamic signals. For instance, nuclear condensates respond to oscillations in transcription facto…
Intermediate physical interactions induce spatiotemporal dynamics in Turing patterns
Cathelijne ter Burg, David Zwicker
Turing patterns are a central paradigm for describing spatial patterns in nature. The corresponding theory of reaction-diffusion dynamics combines ideal diffusion with nonlinear re…
Roadmap for Condensates in Cell Biology
Dilimulati Aierken, Sebastian Aland, Stefano Bo +38
Biomolecular condensates govern essential cellular processes yet elude description by traditional equilibrium models. This roadmap, distilled from structured discussions at a works…
Molecular simulations of phase separation in elastic polymer networks
Takahiro Yokoyama, Yicheng Qiang, David Zwicker +1
Phase separation within polymer networks plays a central role in shaping the structure and mechanics of both synthetic materials and living cells, including the formation of biomol…
Phase separation with non-local interactions
Filipe C. Thewes, Yicheng Qiang, Oliver W. Paulin +1
Phase separation in complex systems is a ubiquitous phenomenon. While simple theories predict coarsening until only macroscopically large phases remain, concrete models often exhib…
Advection selects pattern in multistable emulsions of active droplets
Stefan Köstler, Yicheng Qiang, Guido Kusters +1
Controlling the size of droplets, for example in biological cells, is challenging because large droplets typically outcompete smaller droplets due to surface tension. This coarseni…
Physical interactions enable energy-efficient Turing patterns
Cathelijne ter Burg, David Zwicker
Patterns are ubiquitous in nature, but how they form is often unclear. Turing developed a seminal theory to explain patterns based on reactions that counteract the equalizing tende…
Dynamics of phase separation in non-local elastic networks
Oliver W. Paulin, Yicheng Qiang, David Zwicker
Phase separation of a liquid mixture embedded within an elastic network is relevant to a wide range of natural and industrial systems, including biomolecular condensates interactin…
Self-propulsion via non-transitive phase coexistence in chemically active mixtures
Yicheng Qiang, Chengjie Luo, David Zwicker
Phase separation drives the formation of biomolecular condensates in cells, which comprise many components and sometimes possess multiple phases. The equilibrium physics of phase s…
Could Living Cells Use Phase Transitions to Process Information?
Arvind Murugan, David Zwicker, Charlotta Lorenz +1
To maintain homeostasis, living cells process information with networks of interacting molecules. Traditional models for cellular information processing have focused on networks of…
Active viscoelastic condensates provide controllable mechanical anchor points
Oliver W. Paulin, Júlia Garcia-Baucells, Luise Zieger +3
Many biological materials must couple mechanical strength with the ability to rapidly self-assemble at a specific location. In particular, biomolecular condensates readily self-ass…
Chemically active droplets in crowded environments
Jacques Fries, Roxanne Berthin, Chengjie Luo +4
Biomolecular condensates are essential for cellular organization and result from phase separation in systems far from thermodynamic equilibrium. Among various models, chemically ac…
