FIG. 1.

(a) A hydrodynamic trap is created by a planar extensional flow field at the junction of two perpendicular microchannels. (b) The velocity field (top) and the potential well (bottom) for a particle in the flow field at the microchannel junction.

Image of FIG. 2.
FIG. 2.

(a) Hydrodynamic forces acting on particles in the flow field. (b) and (c) Steering the particle by manipulating the stagnation point (cross) along the extensional axis.

Image of FIG. 3.
FIG. 3.

(a) Trajectory for a trapped particle along the extensional axis (squares). When the particle is released from the trap (arrow), it escapes along one of the outlet channels (circles). Insets: (Bottom) Rescaled particle trajectory between 120–280 s. (Top) Micrograph of a bead trapped at the stagnation point. (b) Power spectrum of a trapped polystyrene bead ( diameter) along the extensional axis. Inset: Histogram of displacements of a trapped bead ( diameter) from the trap center.
