Magnetic Lateral Ladder for Unidirectional Transport of Microrobots: Design Principles and Potential Applications of Cells‐on‐Chip (Small 9/2024)

摘要

Microrobots In article number 2305528, Byeonghwa Lim, CheolGi Kim, and co-workers introduced a novel approach to address challenges in controlling functionalized microrobots. By using an asymmetric magnetic texture resembling a lateral ladder, termed the “railway-track,” precise unidirectional movement is achieved, enabling versatile microrobot manipulation in cells-on-chip platform. This concept allows for complex tasks, like targeted collection, controlled transport, and local mixing, advancing micro-robotics beyond traditional magnetic field-based control methods.
