Recent Advances in Liquid Metal Manipulation toward Soft Robotics and Biotechnologies

Interest has grown significantly in the field of soft robotics, which seeks to develop machinery capable of duplicating the elastic and rheological properties of typically polymeric or elastomeric biological tissues and organs. As a result of a number of unique properties, gallium-based liquid metals (LMs) are emerging as materials used in the forefront of soft robotics research. Finding methods to enable the sophisticated manipulation of LMs will be essential for further progress in the field. This review provides a critical discussion of the manipulation of LMs and on important biotechnological applications of LMs including microfluidics, healthcare devices, biomaterials, and nanomedicines.
