Nanoarchitectonics and Applications of Gallium‐Based Liquid Metal Micro‐ and Nanoparticles

Abstract In recent years, gallium‐based liquid metal (GLM) is an attractive material because of its excellent characteristics such as ultra‐low melting point, high fluidity, high conductivity, self‐healing and so on. GLMs have unique properties at micro and nano scales, such as core‐shell structure, sinterability, biocompatibility and photothermal conversion ability and so on, which promote the development of relevant application directions. Therefore, various preparation methods of GLM particles and conductive connection of GLM nanoparticles through various sintering methods are reviewed in this paper. In addition, GLM particles also show great prospects in flexible circuits, sensor detection, medical treatment, energy production and other fields
