Chemotaxis is a fundamental bacterial response mechanism to changes in chemical
gradients of specific molecules known as chemoattractant or chemorepellent. The …

Microfluidics is revolutionizing the way we study the motile behavior of cells, by enabling
observations at high spatial and temporal resolution in carefully controlled …

Microorganism sensing of and responding to ambient chemical gradients regulates a myriad
of microbial processes that are fundamental to ecosystem function and human health and …

We have developed a user-friendly microfluidic device for the study of gradient-mediated
bacterial behaviors, including chemotaxis. This device rapidly establishes linear …

A three-point microfluidic system was developed and used to experimentally verify bacterial
chemotaxis with known chemoeffectors. Using pneumatically-controlled micro-valves, the …

Chemotaxis allows bacteria to approach sources of attractant chemicals or to avoid sources
of repellent chemicals. Bacteria constantly monitor the concentration of specific …

Diffusion-based microfluidic devices can generate steady, arbitrarily shaped chemical
gradients without requiring fluid flow and are ideal for studying chemotaxis of free-swimming …

The plug-in-pond and capillary assays are convenient methods for measuring attractant and
repellent bacterial chemotaxis. However, these assays do not provide quantitative …

Bacterial chemotaxis is a complex response to temporal changes of concentrations of
chemoeffectors. Conventional methods, including microfluidic approaches, for the precise …

Motile bacteria bias the random walk of their motion in response to chemical gradients by
the process termed chemotaxis, which allows cells to accumulate in favorable environments …
