Electrophoresis of a non-conducting Newtonian drop of low electrical potential normal to a plane

Electrophoresis of a soft particle normal to a plane

“…They found that the electrophoretic mobility would increase in general, due to the effect of shear thinning. Lee et al [12] considered the situation of a Newtonian liquid drop. The internal flow within the liquid drop was found to reduce the shear rate at the liquid-liquid interface and hence increase the mobility in comparison with the corresponding hard sphere situation.…”

Mechanistic studies of droplet electrophoresis: A review

“…These differences have to be taken into account to accurately describe droplet EP, and will be further elaborated upon next. Generally speaking, droplets move faster, compared to rigid particles with similar ‐potential, because of a smaller effective hydrodynamic drag force exerted on them [41, 44, 65, 66].…”

“…This internal flow will decrease the drag force at the droplet–electrolyte interface. So, the EP mobility of the droplets would be higher compared to the particles with similar ‐potential [41, 44, 65, 66].…”

“…By increasing the ionic strength of the electrolyte, the EDL thickness is decreased and the electrical potential gradient () on the droplet surface will be larger. This creates higher electric driving force and as a result, the EP mobility of the droplet increases [66]. Bailes et al.…”

“…The development of internal flow inside droplets, as a result of the slip arising from the flow field outside the droplet, is a known phenomenon in droplet transport [41, 44, 65, 78, 86]. As mentioned previously, vortices are formed as a consequence of continuous velocity field at the droplet–electrolyte interface [41, 44, 65, 66, 111]. This internal flow reduces the hydrodynamic drag force exerted on the droplets leading to an increase in their EP mobility, compared to particles with similar ‐potential.…”
