Abstract
One example of systems and methods for inertio-elastic focusing of particles in microchannels includes a substrate including a channel having an inlet and an outlet. A viscoelastic fluid, i.e., a fluid having a dynamic viscosity that varies with shear rate, and that carries suspended particles is driven through the channel. The volumetric flow rate at which the fluid is driven results in the formation of a localized pathline in the fluid at or near a center of the channel. The localized pathline defines a width that is equal to or slightly greater than a hydraulic diameter of the particle. The particles in the fluid are focused into the localized pathline.
