Micromanipulation: Dumbbell Fluidic Tweezers for Dynamical Trapping and Selective Transport of Microobjects (Adv. Funct. Mater. 1/2017).

On page 1604571, L. Zhang and co‐workers introduce a new design of a magnetic micromachine for significantly enhanced fluidic trapping, which has a dumbbell‐shape, composed of a nickel nanowire and two polystyrene microbeads. The magnetic dumbbell‐like micromachines are capable of performing dynamical trapping and implement on‐demand transport of microscale objects with induced microvortices in three locomotion modes, i.e., tumbling, wobbling, and rolling.
