Liquids do not have a definite shape, which depend on the shape of the container. Structured liquid is a new type of soft materials based on the self-assembly and jamming transition of colloidal particles at liquid/liquid interfaces. Here, the research progress in the construction of new structured liquids using nanoparticle surfactants (NPSs) assembly at liquid/liquid interfaces is summarized. The promising applications of structured liquids in the fields of packaging, separation, catalysis, energy storage and biomedicine are introduced. In the future, more studies will focus on the development of new functional NPSs, the construction of multiresponsive, structured all-liquid systems, and the extension of the functional applications of structured liquids.
