Abstract

Optical chromatography achieves microscale optical manipulation through the balance of optical and hydrodynamic forces on micron sized particles entrained in microfluidic flow traveling counter to the propagation of a mildly focused laser beam. The optical pressure force on a particle is specific to each particle’s size, shape and refractive index. So far, these properties have been exploited in our lab to concentrate, purify and separate injected samples. But as this method advances into more complex optofluidic systems, a need to better predict behavior is necessary. Here, we present the development and experimental verification of a robust technique to simulate particle trajectories in our optical chromatographic device. We also show how this new tool can be used to gather better qualitative and quantitative understanding in a two component particle separation.

Fig. 1.

An illustration of our three-layer fused silica optical chromatography separation device with fittings for injection, inlet and outlet connections. The exploded view shows the separation region with blue arrows indicating flow direction and red arrows indicating the propagation direction of the laser focused into the device. The laser focal point is positioned at the inlet wall with a diameter of about 36 microns and defocuses to fill the capillary at the opposite wall. The subset image shows a view of the separation region and capillary in the actual device through the 20x objective. The capillary is 500μm in length, with a slight taper of less than 1° to the center, and 55μm at each end.

Trajectory for a single 1.9μm PS particle at 20nl/min flow and 2W laser power (1.9W in the channel). (a) Experimental track from an image series collected at 2Hz (Media 1). The initial position from the wall and the maximum particle entrance distance are indicated. (b) Simulated trajectory using the experimental conditions with a resulting entrance depth of 83μm.

Fig. 3.
Fig. 3.

Plot of flow rate and particle entrance distance for six different flow rates ranging from 5 to 20nl/min. The black circles are the average experimental values and standard deviation. The red line connects simulated values calculated under the same conditions at each experimental flow rate.

Fig. 4.

Trajectories for simulated pure injections of (a) 1.9μm PS and (b) 1.0μm silica at a power of 1.9W (in the channel) and 20nl/min flow. The trajectories clearly illustrate that the PS particles are retained much more than the Si particles. Accompanying videos show the time progression of particles through the simulation and give a more dynamic feel to the simulation for these results (Media 2).
