In vitro bacterial behavioral experiments using a microchannel with folds. a Schema of the microfluidics device with many folds. A suspension of E. coli flows from the inlet to the outlet. b, c Probability density distribution varied with the position in the microchannel from the center to the fold, and the inset indicates the trajectory of the flow; r is the coordinate from the center to the wall, and R is the position at the bottom of the folds: b E. coli, c particles. The line represents the mean, and the shaded regions indicate standard deviations (N = 5)
