From: Microfluidics unveils role of gravity and shear stress on Pseudomonas fluorescens motility and biofilm growth

Fig. 4

Motility coefficient μ, analogous to Fick’s diffusion coefficient, calculated for the bottom (in black) and top (in red) surfaces of the microfluidic channel at various flow hours. Each row represents different shear rate values imposed. a The first column reports isotropic motility coefficient, calculated according to Eq. 7. b Analysis of the same trajectories as plotted in column A, focusing on the MSD along the x-axis (flow direction) only. c Analysis of the same trajectories as plotted in column A, considering the Mean Squared Displacement (MSD) along the y-axis (orthogonal to the flow direction) only.
