Pickering emulsions are emulsions stabilized by colloidal surfactants, i.e. solid particles. Compared with traditional molecular surfactant-stabilized emulsions, Pickering emulsions show many advantages, such as high resistance to coalescence, long-term stability, good biocompatibility and tunable properties. In recent years, Pickering emulsions are widely applied in scientific researches and industrial applications. In this review, we focus on the influences of particle properties on Pickering emulsions, including particle amphiphilicity, concentration, size and shape, and summarize the strategies developed for the preparation of amphiphilic Janus particles. The applications of Pickering emulsions in food industry, cosmetic industry, material science, drug delivery, biomedical research and vaccine adjuvant will also be covered. Pickering emulsions are a unique system for multi-disciplinary studies and will become more and more important in the future.

Pickering乳液是由胶体表面活性剂即固体颗粒稳定的乳液。与传统的分子表面活性剂稳定乳液相比，Pickering乳液具有抗聚结能力强、长期稳定性好、生物相容性好、性能可调等优点。近年来，Pickering乳液在科学研究和工业应用中得到广泛应用。在这篇综述中，我们关注粒子性质对 Pickering 乳液的影响，包括粒子两亲性、浓度、大小和形状，并总结了为制备两亲 Janus 粒子而开发的策略。Pickering乳液在食品工业、化妆品工业、材料科学、药物输送、生物医学研究和疫苗佐剂中的应用也将涵盖在内。
