A set of local mechanical probes has been developed over the last ten years, allowing a
kind of dynamical mechanical testing known as microrheology. This paper provides a short …

We review the dynamics of particle laden interfaces, both particle monolayers and particle+
surfactant monolayers. We also discuss the use of the Brownian motion of microparticles …

Optical imaging and analysis of single molecules continue to unfold as powerful ways to
study the individual behavior of biological systems, unobscured by ensemble averaging …

Regulated protein-protein interactions are critical for cell signaling, differentiation, and
development. For the study of dynamic regulation of protein interactions in vivo, there is a …

Inhaled antibiotic treatment of cystic fibrosis-related bacterial biofilm infections is challenging
because of the pathological environment of the lungs. Here, we present an “environment …

The actin cytoskeleton represents a key regulator of multiple essential cellular functions in
both eukaryotes and prokaryotes. In eukaryotes, these functions depend on the orchestrated …

Microrheology offers several advantages over traditional macroscopic rheology: the use of
very small samples, the possibility of studying heterogeneous samples and the broad range …

Lipases are interfacially activated enzymes that catalyze the hydrolysis of ester bonds and
constitute prime candidates for industrial and biotechnological applications ranging from …

Products from polymerization have influenced our daily lives tremendously over the past
hundred years. It is therefore not surprising that enormous efforts have been and are being …

Achieving mechanistic understanding of transport in complex environments such as inside
cells or at polymer interfaces is challenging. We need better ways to image transport in 3-D …
