Creating localized mixing stations within microfluidic channels
- Simulations show how the flow and phase behavior of binary fluids in microchannels can be regulated by introducing solvophilic and solvophobic patches onto the underlying substrate. Depending on the arrangement of these patches, the two fluids can be driven to "switch" positions or undergo extensive mixing within a specific region of the channel. The results open the possibility for creating spatially controlled reaction chambers within microfluidic devices.
