Magnetic zigzag structures as cell microgripper

What is it about?

A cell microgripper was designed here that used magnetic field for actuation. Single domain magnetic thin films were deposited on the microgripper such that the magnetic torque can be transferred to the mechanical structure. A hysteresis characteristic of the microgripper arms’ displacement was observed in the actuation. In addition, we also demonstrated the gripping of a single cell in water solution using the designed cell microgripper.
