It is found that the boundary effect in terms of the reduction of droplet mobility (droplet velocity per unit strength of the applied electric field) is very significant when the double layer surrounding the droplet is thick, and diminishes as it gets very thin. Moreover, the viscosity ratio of the ambient fluid to the internal one, £m, is a crucial factor in determining its electrophoretic behavior. The boundary effect is less significant as the viscosity ratio gets high. Up to 70% mobility reduction is observed when this ratio is low (£m = 0.01), whereas only 40% reduction when it is high (£m = 100). The results of this study can be utilized in various fields of biotechnology, such as a biosensor or a lab-on-a-chip device. |
