Depinning and activated motion of chiral self-propelled robots
Juan Pablo Carrillo-Mora, Adrià Garcés, Demian Levis
We study experimentally, numerically and analytically, the dynamics of a chiral active particle (cm-sized robots), pulled at a constant translational velocity. We show that the sys…
Preventing clustering of active particles in microchannels
Juan Pablo Carrillo-Mora, Moniellen Pires Monteiro, V. I. Marconi +3
The trajectories of microswimmers moving in narrow channels of widths comparable to their sizes are significantly altered when they encounter another microswimmer moving in the opp…
Soil-mimicking microfluidic devices reveal restricted flagellar motility of Bradyrhizobium diazoefficiens under microconfinement
Moniellen Pires Monteiro, Juan Pablo Carrillo-Mora, Nahuel Gutiérrez +4
Bradyrhizobium diazoefficiens is a nitrogen-fixing symbiont of soybean, worldwide used as biofertilizer. This soil bacterium possesses two flagellar systems enabling it to swim in…
Damage and recovery of flagella in soil bacteria exposed to shear within long microchannels
Juan Pablo Carrillo-Mora, Moniellen Pires Monteiro, AnÃbal R. Lodeiro +2
The swimming motility of bacteria is driven by the action of bacterial flagellar motors, whose outermost structure is a long and thin helicoidal filament. When rotated, the fluid m…
