Hydrogels are increasingly employed as multidimensional cell culture platforms often with a
necessity that they respond to or control the cellular environment. Specifically, synthetic …

In microrheology, the local and bulk mechanical properties of a complex fluid are extracted
from the motion of probe particles embedded within it. In passive microrheology, particles …

This book presents a comprehensive overview of microrheology, emphasizing the
underlying theory, practical aspects of its implementation, and current applications to …

Research on soft materials, including colloidal suspensions, glasses, pastes, emulsions,
foams, polymer networks, liquid crystals, granular materials, and cells, has captured the …

We report the first measurements of the intrinsic strain fluctuations of living cells using a
recently developed tracer correlation technique along with a theoretical framework for …

It is now widely appreciated that normal tissue morphology and function rely upon cells'
ability to sense and generate forces appropriate to their correct tissue context. Although the …

We derive the Markovian description for the nonequilibrium Brownian motion of a heated
nanoparticle in a simple solvent with a temperature-dependent viscosity. Our analytical …

Quantitatively measuring the mechanical properties of soft matter over a wide range of
length and time scales, especially if a sample is as complex as typical biological materials …

We demonstrate how tracer microrheology methods can be extended to study submicron
scale variations in the viscoelastic response of soft materials; in particular, a semidilute …

We measure the linear viscoelasticity of sterically entangled and chemically cross-linked
networks of actin filaments over more than five decades of frequency. The high-frequency …
