This front cover conceptually demonstrates a biomimetic cellular-eating phenomenon in roomtemperature liquid metal which is called Liquid Metal Phagocytosis. During the process, tiny liquid metal “cells” intake micro or nano metal particles in an aqueous environment upon applying an electrical polarization or other excitations. The underlying mechanisms are discussed in article number 1700024 by Jianbo Tang, Jing Liu, and co-workers.
