A biofilm is an interface-associated colloidal dispersion of bacterial cells and excreted
polymers in which microorganisms find protection from their environment. Successful …

Microorganisms often live in habitats characterized by fluid flow, from lakes and oceans to
soil and the human body. Bacteria and plankton experience a broad range of flows, from the …

The locomotion of microorganisms and spermatozoa in complex viscoelastic fluids is of
critical importance in many biological processes such as fertilization, infection, and biofilm …

The physics of active liquid crystals is mostly governed by the interplay between elastic
forces that align their constituents, and active stresses that destabilize the order with …

Electrochemical impedance spectroscopy (EIS) is a non-disruptive technique that can be
used to assess the corrosion behavior of materials. In this work, case studies on microbial …

We use active nematohydrodynamics to study the flow of an active fluid in a 3D
microchannel, finding a transition between active turbulence and regimes where there is a …

Fluid flow is thought to prevent bacterial adhesion, but some bacteria use adhesins with
catch bond properties to enhance adhesion under high shear forces. However, many …

Bacteria often thrive in surface-attached communities, where they can form biofilms affording
them multiple advantages. In this sessile form, fluid flow is a key component of their …

Surface-attached cells can sense and respond to shear flow, but planktonic (free-swimming)
cells are typically assumed to be oblivious to any flow that carries them. Here, we find that …

Microbes thrive in diverse porous environments—from soil and riverbeds to human lungs
and cancer tissues—spanning multiple scales and conditions. Short-to long-term …
