Several complementary techniques have been developed in recent years that make it possible
to measure viscoelastic properties of soft materials on micrometer scales. Such methods …

All substances exhibit constant random motion at the microscopic scale. This is a direct
consequence of thermal agitation, and leads to diffusion of molecules and small particles in a …

The mechanical properties of soft biological tissues are essential to their physiological function
and cannot easily be duplicated by synthetic materials. Unlike simple polymer gels, many …

Networks of cross-linked and bundled actin filaments are ubiquitous in the cellular cytoskeleton,
but their elasticity remains poorly understood. We show that these networks exhibit …

We develop a model for cross-linked gels and sterically entangled solutions of semiflexible
biopolymers such as F-actin. Such networks play a crucial structural role in the cytoskeleton …

Cells both actively generate and sensitively react to forces through their mechanical framework,
the cytoskeleton, which is a nonequilibrium composite material including polymers and …

Cytoskeletal microtubules have been proposed to influence cell shape and mechanics
based on their ability to resist large-scale compressive forces exerted by the surrounding …

From seashells to DNA, chirality is expressed at every level of biological structures. In self-assembled
structures it may emerge cooperatively from chirality at the molecular scale. …

A new scanning probe-based microrheology approach is used to quantify the frequency-dependent
viscoelastic behavior of both fibroblast cells and polymer gels. The scanning probe …
