颗粒粘附到流体-流体界面的能力可以稳定乳液的形成。当封装的流体是液体并且其浸入的流体是空气时，形成的物体被称为“液体大理石”。在这里，我们将讨论如何创建液体大理石，它们的基本属性及其运输和潜在用途。我们展示了它们是如何自然产生的昆虫废物处理系统，从液滴对粉末和疏水性土壤的影响，以及含液体颗粒的混合。我们的主要目的是审查宏观单一大理石及其在传感器和液滴微流体的潜在用途的研究。然而，我们也说明了液体大理石，皮克林乳液和“干水”之间的相似性，以及化妆品和药物制剂中的液体大理石组件的潜在应用。最后，我们讨论了如何修改颗粒的表面结构，并提供颗粒（如Janus颗粒）上的异质表面化学可能会提供新类型的液体大理石和应用。
The ability of particles to adhere to a fluid-fluid interface can stabilize the formation of an emulsion. When the encapsulated fluid is a liquid and the fluid in which it is immersed is air, the object formed is called a "Liquid Marble". Here we discuss how liquid marbles can be created, their fundamental properties and their transport and potential uses. We show how they arise naturally as an insect waste disposal system, from impact of droplets on powders and on hydrophobic soil, and in the mixing of particulate containing liquids. Our principal aim is to review research on macroscopic single marbles and their potential uses in sensors and droplet microfluidics. However, we also illustrate the similarity between liquid marbles, Pickering emulsions and "Dry Water", and the potential application of assemblies of liquid marbles within cosmetics and pharmaceutical formulations. Finally, we discuss how modifying the surface structure of particles and providing heterogeneous surface chemistry on particles (e.g. Janus particles) might provide new types of liquid marbles and applications.
