As one increases the concentration of a colloidal suspension, the system exhibits a dramatic
increase in viscosity. Beyond a certain concentration, the system is said to be a colloidal …

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 is the latest edition to the Cambridge Series in Chemical Engineering, a series
dedicated to meeting the needs of professionals and academics in this field. This is an …

Laser trapping has served as a useful tool in physics and biology, but, before our work,
chemists had not paid much attention to this technique because molecules are too small to …

Microrheology was proposed almost twenty years ago as a technique to obtain rheological
properties in soft matter from the microscopic motion of colloidal tracers used as probes …

We present a data analysis procedure that provides the solution to a long-standing issue in
microrheology studies, ie the evaluation of the fluids' linear viscoelastic properties from the …

Multiple particle tracking microrheology (MPT) is a passive microrheological technique that
measures the Brownian motion of probe particles embedded in a sample to characterize …

Over the past few decades, microrheology has emerged as a widely used technique to
measure the mechanical properties of soft viscoelastic materials. Optical tweezers offer a …

Microrheological study of complex fluids traces its roots to the work of the botanist Robert
Brown in the early nineteenth century. Indeed, passive microrheology and Brownian motion …

We introduce active, probe-based microrheological techniques for measuring the flow and
deformation of complex fluids. These techniques are ideal for mechanical characterization …
