Rheology of two-dimensional F-actin networks associated with a lipid interface
arXiv:0709.2182 · doi:10.1103/PhysRevE.77.011909
Abstract
We report on the surface rheology of cross-linked F-actin networks associated with a lipid monolayer at the air-water interface of a Langmuir monolayer. The rheological measurements are made using a Couette cell. These data demonstrate that the network has a finite elastic modulus that grows as a function of the cross-linking concentration. We also note that under steady-state flow the system behaves as a power law fluid in which the effective viscosity decreases with imposed shear.
