Summary: Researchers have developed an on-demand micromixer based on magnetic microwalls, which can achieve controllable mixing and complete mixing shut-off in commercial microfluidic devices. The microwalls can create a meandering path in the main channel to enable mixing or open up the channel to stop mixing, controlled by a simple magnet. Experimental results show that the microwalls can effectively enhance mixing in colored fluids with different flow rates and viscosities.
