As we mentioned above, the electrokinetic mechanisms, which includes electrophoresis, DEP, ACEO, electrothermal effect, and electro-orientation, are main driving force for particle manipulation using an optoelectrofluidic device. In addition, we could also observe the electrostatic interactions due to the polarization of dielectric particles like cells.

If a clinker sample is to be subjected to the extraction, a random sample of 1- to 2-mm crushed clinker particles, taken from the same fraction as previously prepared for polished section examination, is further crushed in a mortar and pestle until all the subsample passes a 75- j,m screen (No. 200 mesh). If acement is to be treated, a random sample of approximately 10 grams is sieved to produce the 45- to 75-pm fraction (325 to 200 mesh) particles left on the 75- j,m screen could be further crushed to pass the screen or, perhaps, studied microscopically to determine belite nest percentage. Sieving, however, is an optional step the main benefit is that it provides a uniformly sized powder promoting a relatively uniform level of focus by removing "boulders" that may interfere with examination and particle manipulation. If sieve confaminafion is a likely problem, one can use disposable nylon with the proper mesh opening.

Analogous to electrophoresis, diffusiophoresis is of practical importance in some applications to particle characterization and separation. In the metal and rubber technologies concerning surface treatment, diffusiophoresis is a transport mechanism in certain latex-particle coating processes. Being an efficient means to drive particles in nonuniform solutions, diffusiophoresis finds important applications in the area of particle manipulation in microfluidic or lab-on-a-chip devices and autonomous motions of micro/ nanomotors [8]. On the other hand.
