Ion-partitioning effect promotes electroosmotic mixing of non-Newtonian fluids in soft-patterned microchannel

Key Points

• Electroosmotic mixing is improved through the ion-partitioning effect in non-Newtonian fluids, enhancing fluid interaction.
• Key evidence shows that the presence of a polyelectrolyte layer significantly influences mixing dynamics.
• Numerical simulations demonstrate fluid behavior within a micromixer featuring patterned soft polyelectrolyte layers.
• Findings indicate potential applications for more efficient fluid mixing in microfluidic devices.
