Structural anisotropy and orientation-induced Casimir repulsion in fluids

, 2001
In this work we theoretically consider the Casimir force between two periodic arrays of nanowires (both in vacuum, and on a substrate separated by a fluid) at separations comparable to the period.

Ultrasensitivity of Cell Adhesion to the Presence of Mechanically Strong Ligands

Physical Review X, 2016
Integrins, a class of membrane proteins involved in cell adhesion, participate in the cell’s sensing of the mechanical environments. We previously showed that, for the initial cell adhesion to occur, single integrins need to experience a threshold force ...

A constrained random-force model for weakly bending semiflexible polymers

, 2011
The random-force (Larkin) model of a directed elastic string subject to quenched random forces in the transverse directions has been a paradigm in the statistical physics of disordered systems. In this brief note, we investigate a modified version of the
