Lab on a chip platform for measuring the encounter rates of marine bacteria with crude oil droplets

The encounter rate of motile bacteria with passive solid particles and microdroplet droplets was measured and studied. The bacteria strain studied here is Pseudomonas P62 and the solid particles are 1 micron size latex spheres. We generated pendent droplet with different sizes pinned in microfluidic channels. Files included are raw and processed image sequences of experiments. These data are used to obtain colloids positions and their trajectories. The velocity fields and dispersion coefficients of the particles also are measured are different flow rates.
