To investigate how particle shape influences electrophoretic velocity in viscoelastic fluids.
Demonstrated particle shape dependence of electrophoresis in viscoelastic poly(ethylene oxide) solutions.
Altered particle shapes from sphere to pear and peanut to analyze effects on velocity.
Examined effects in different concentrations of PEO solutions.
Shape change from sphere to pear or peanut enhances electrophoretic velocity significantly.
The effect is absent in Newtonian fluids and increases with higher PEO concentrations.
Fluid elasticity plays a critical role in modifying particle behavior during electrophoresis.
