Design of a Reconfigurable Microfluidic System Enabled by Magnetic Miniature Robots

Advanced Intelligent Systems, EarlyView.
Magnetic miniature robots are integrated into microfluidic chips to achieve real‐time reconfiguration. By external magnetic actuation, the robots perform sorting, mixing, flow regulation, and bubble removal on demand. This versatile platform eliminates the need for complex on‐chip hardware and enables adaptive control for biological and chemical ...
