Accumulation and depletion of E. coli in surfaces mediated by curvature
Benjamín Pérez-Estay, María Luisa Cordero, Néstor Sepúlveda +1
Can topography be used to control bacteria accumulation? We address this question in the model system of smooth-swimming and run-and-tumble \textit{Escherichia coli} swimming near…
Bacteria driving droplets
Gabriel Ramos, Maria Luisa Cordero, Rodrigo Soto
We confine a dense suspension of motile \textit{Escherichia coli} inside a spherical droplet in a water-in-oil emulsion, creating a "bacterially" propelled droplet. We show that dr…
Local details versus effective medium approximation: A study of diffusion in microfluidic random networks made from Voronoi tessellations
Washington Ponce, Maria Luisa Cordero
We measured the effective diffusion coefficient in regions of microfluidic networks of controlled geometry using the FRAP (Fluorescence Recovery After Photobleaching) technique. Th…
Magnetotactic bacteria in a droplet self-assemble into a rotary motor
Benoit Vincenti, Gabriel Ramos, Maria Luisa Cordero +3
From intracellular protein trafficking to large scale motion of animal groups, the physical concepts driving the self-organization of living systems are still largely unraveled. Se…
The effect of confinement on the deformation of microfluidic drops
Camilo Ulloa, Alberto Ahumada, María Luisa Cordero
We study the deformation of drops squeezed between the floor and ceiling of a microchannel and subjected to a hyperbolic flow. We observe that the maximum deformation of drops depe…
Quantitative analysis of the dripping and jetting regimes in co-flowing capillary jets
María Luisa Cordero, François Gallaire, Charles N. Baroud
We study a liquid jet that breaks up into drops in an external co-flowing liquid inside a confining microfluidic geometry. The jet breakup can occur right after the nozzle in a phe…
