摘要
The phenomenon of adsorption of solid particles at fluid interfaces to stabilize emulsions or foams have been known for more than a century.Today,particle-stabilized emulsions,often referred to as Pickering emulsions,are receiving growing attention as they are encountered in oil recovery and have long been used in personal care products and food industry.Over the past 10 years the focus of the Pickering emulsion has also increasingly shifted to biomedical applications with thanks to novel syntheses of a wide range of biocompatible particle stabilizers.Here,a brief overview of the development of biocompatible particles is given for Pickering emulsion stabilization,including alginate,poly(lactic-co-gIycolic acid)(PLGA),and protein-based particles.The materials prepared by templating from emulsion stabilized with biocompatible particles include colloidal capsules and hierarchically porous materials.It is hoped that the understanding gained from the recent intense activity in the field will enable more researchers to modify existing materials and design new formulations,which would be beneficial for exploring more biological applications.
