Microrobots
In article number 2310084, Salvador Pané, Minsoo Kim, Hao Ye, and co‐workers introduce microrobotic superstructures comprising a magnetic gelatin composite chassis threaded with iron helical micromachines. Magnetic inputs can be used to navigate the superstructure (gradients) and also dissolve the chassis through magnetic hyperthermia, thereby releasing the micromachines to navigate through...
Magnetic microrobots have been developed for navigating microscale environments by means of remote magnetic fields. However, limited propulsion speeds at small scales remain an issue in the maneuverability of these devices as magnetic force and torque are proportional to their magnetic volume. Here, a microrobotic superstructure is proposed, which, as analogous to a supramolecular system, consists...
