Chemokinesis-Driven Accumulation of Active Colloids in Low-Mobility Regions of Fuel Gradients
Jeffrey L. Moran, Philip M. Wheat, Nathan A. Marine +1
Many motile cells exhibit migratory behaviors, such as chemotaxis (motion up or down a chemical gradient) or chemokinesis (when speed depends on concentration), which enable them t…
Two-orders of magnitude improvement detection limit of lateral flow assays using isotachophoresis
Babak Y. Moghadam, Kelley T. Connelly, Jonathan D. Posner
Lateral flow (LF) immunoassays are one of the most prevalent point-of-care (POC) diagnostics due to their simplicity, low cost, and robust operation. A common criticism of LF tests…
Role of Solution Conductivity in Reaction Induced Charge Auto-Electrophoresis
Jeffrey L. Moran, Jonathan D. Posner
Catalytic bimetallic Janus particles swim by a bipolar electrochemical propulsion mechanism that results from electroosmotic fluid slip around the particle surface. The flow is dri…
Locomotion of Electrocatalytic Nanomotors due to Reaction Induced Charge Auto-Electrophoresis
J. L. Moran, P. M. Wheat, J. D. Posner
Bimetallic rod-shaped nanomotors swim autonomously in hydrogen peroxide solutions. Here we present a scaling analysis, computational simulations, and experimental data that show th…
Tornadoes in a Microchannel
Carlos L. Perez, Jonathan D. Posner
In non-dilute colloidal suspensions, gradients in particle volume fraction result in gradients in electrical conductivity and permittivity. An externally applied electric field cou…
