This system is validated by observing the neutrophil migration in three different conditions: 1) medium control, 2) uniform IL-8 control, and 3) IL-8 gradient. The results show that neutrophils exhibit random migration in both medium and uniform IL-8 control experiments, while they show strong directional migration to the IL-8 gradient. These results successfully validated the developed UMCAS system.

Abstract: Microspheres are sorted by resonant light pressure effects. An evanescent optical field is generated when light is confined within the interior of an optical element such as a surface waveguide, a tapered microfiber, or a prism. Microspheres brought within vicinity of the surface are subjected to forces that result from a coupling of the evanescent field to whispering gallery modes (WGM) in the microspheres. Alternatively, a focused laser beam is directed close to the edge of the microspheres to exert resonant optical forces on microspheres. Alternatively, standing optical waves are excited in the optical element. Optical forces are resonantly enhanced when light frequencies match WGM frequencies in the microspheres. Those microspheres for which resonance is obtained are more affected by the evanescent field than microspheres for which resonance does not occur. Greater forces are applied to resonating microspheres, which are separated from a heterogeneous mixture according to size.
