Micro/Nanomotors: Phoretic Liquid Metal Micro/Nanomotors as Intelligent Filler for Targeted Microwelding (Adv. Mater. 51/2019)

In article number 1905067, Wei Wang, Xing Ma, and co-workers report the fabrication of a liquid metal micro/nanomotor (LM-MNM) made of Galinstan (a gallium–indium–tin alloy). These small LM-MNMs (with a size of a few hundred nanometers) are half-coated with a thin layer of platinum (Pt) and move in H2O2 via self-electrophoresis. Their potential as an on-demand, self-targeting welding filler is demonstrated through their movement and accumulation at junctions in a silver nanowire network.
