Topology of Nonequilibrium Currents Controls Active Transport
A. Escobar, G. Geva, A. Alexander-Katz +3
Structured environments repeatedly redirect active particles, producing transport pathways that cannot be readily inferred from individual trajectories. Here, we show that the larg…
Mechanical performance of hybrid polymer-lipid vesicles with leaflet asymmetry engineered using microfluidics
Yuting Huang, Arash Manafirad, Simon Matoori +6
Lipid vesicles consist of aqueous cores surrounded by a bilayer of phospholipids. Hybrid polymer-lipid vesicles incorporate both polymers and lipids, offering promising properties…
Membrane-mediated force transduction: Stick-slip motion of vesicles with fluid membranes
Paula Magrinya, Arin Escobar Ortiz, Juan L. Aragones +1
How internal forces are transduced into motion through soft, fluid membranes remains a fundamental question in the study of active systems. To investigate this coupling, we develop…
Rolling, sliding and trapping of driven particles in square obstacle lattices
Galor Geva, Arin Escobar, Paula Magrinya +4
Transport phenomena in complex and dynamic microscopic environments are fundamentally shaped by hydrodynamic interactions. In particular, microparticle transport in porous media is…
Rolling vesicles: From confined rotational flows to surface-enabled motion
Paula Magrinya, Pablo Palacios, Pablo Llombart +4
The interaction of surfaces in relative motion in wet environments is dominated by lubrication forces, which play a pivotal role in the dynamics of microscopic systems. Here, we de…
