Particles, Sheared and Suspended (IMAGE) University of Chicago Caption The black-and-white confocal microscopic images above show microscopic particles suspended in a viscous fluid, forming string-like structures while undergoing shear flow. The particles are less densely packed in the image at left. The inset color images visually represent the probability of finding a particle at a particular location if there is already a particle at center.
