FIG. 1.

Experimental arrangement for fiber-focused microfluidic trapping integration. The inset includes illustration of diode bar optical trap within microfluidic flow channel where magnitude of the trapping force normal to the diode bar axis.

FIG. 2.

Predictions of restoring force for (a) wide bar (, long) and (b) spot illumination for PS particles in water. The insets illustrate bar and spot illumination at their positions of maximum restoring force (with arrows indicating direction) for spherical particles of radius.

Image of FIG. 3.
FIG. 3.

(a) Maximum restoring force normalized to provide an effective escape velocity and position of force maximum for bar (◼◻) and spot (●○) illumination. (b) Comparison of modeling predictions (◻) for the maximum restoring force to experimental estimates (◼) based on flow measurements. Predictions of restoring vs wall forces (⊠) with varying particle size. Lines are guides for the eye.
