Bacteria are among the oldest and most abundant species on Earth. Bacteria successfully
colonize diverse habitats and play a significant role in the oxygen, carbon, and nitrogen …

Experimental observations indicate that, at sufficiently high cell densities, swimming bacteria
exhibit coordinated motions on length scales (10 to 100 μm) that are large compared with …

Individual swimming bacteria are known to bias their random trajectories in search of food
and to optimize survival. The motion of bacteria within a swarm, wherein they migrate as a …

Bacteria employ diverse motility patterns in traversing complex three-dimensional (3D)
natural habitats. 2D microscopy misses crucial features of 3D behaviour, but the applicability …

Self-assembly is a promising route for micro-and nano-fabrication with potential to
revolutionise many areas of technology, including personalised medicine. Here we …

We demonstrate a method for the fast, high-throughput characterization of the dynamics of
active particles. Specifically, we measure the swimming speed distribution and motile cell …

We studied the response of swimming Escherichia coli (E. coli) bacteria in a comprehensive
set of well-controlled chemical concentration gradients using a newly developed microfluidic …

We present a survey on the application of fluid approximations, in the form of mean-field
models, to the design of control strategies in swarm robotics. Mean-field models that consist …

Motility is one of the most dynamic features of the microbial world. The ability to swim or
crawl frequently governs how microorganisms interact with their physical and chemical …

We introduce a bifocal imaging method that enables three-dimensional (3D) tracking of both
fluorescent and nonfluorescent particles. We accomplish this by simultaneously imaging a …
