Persistence-driven durotaxis: Generic, directed motility in rigidity gradients
Elizaveta A. Novikova, Matthew Raab, Dennis E. Discher +1
Cells move differently on substrates with different elasticities. In particular, the persistence time of their motion is higher on stiffer substrates. We show that this behavior wi…
Electrostatic cluster formation in lipid monolayers
Wouter G. Ellenbroek, Yu-Hsiu Wang, David A. Christian +3
We study phase separation in mixed monolayers of neutral and highly negatively charged lipids, induced by the addition of divalent positively charged counterions. We find good agre…
Cross-correlated TIRF/AFM shows Self-assembled Synthetic Myosin Filaments are Asymmetric - Implications for Motile Filaments
Andre E. X. Brown, Alina Hategan, Daniel Safer +2
Myosin-II's rod-like tail drives filament assembly with a head arrangement that should generate equal and opposite contractile forces on actin--if one assumes that the filament is…
Effect of Bilayer Thickness on Membrane Bending Rigidity
H. Bermudez, D. A. Hammer, D. E. Discher
The bending rigidity of bilayer vesicles self-assembled from amphiphilic diblock copolymers has been measured using single and dual-micropipet techniques. These copolymers ar…
Elongation and fluctuations of semi-flexible polymers in a nematic solvent
Z. Dogic, J. Zhang, A. W. C. Lau +7
We directly visualize single polymers with persistence lengths ranging from to 16 m, dissolved in the nematic phase of rod-like {\it fd} virus. Polymers with suffi…
Molecular Weight Dependence of Polymersome Membrane Elasticity and Stability
Harry Bermudez, Aaron K. Brannan, Daniel A. Hammer +2
Vesicles prepared in water from a series of diblock copolymers and termed "polymersomes" are physically characterized. With increasing molecular weight , the hydrophobic…
