Nanoscale multiple emulsions, nanoparticles resulting therefrom and methods of making and using thereof are described. The nanoscale multiple emulsions are typically double nanoemulsions, such as oil-in-water-in-oil (O1/W/O2) nanoemulsions, in which nanodroplets of the first oil (O1) phase are suspended in the aqueous (W) phase and together are dispersed in the second oil (O2) phase. The double nanoemulsions are stable with high encapsulation efficiency allowing templating to form multiphase nanoparticles. The multiphase nanoparticles include nanodroplets of O1 phase dispersed in a continuous matrix that can be a liquid, a gel, or a solid at room temperature and pressure. Methods of making the double nanoemulsions include high-energy forces and serial nanoemulsifications.
本文描述了纳米级多重乳液、由此产生的纳米颗粒及其制造和使用方法。纳米级多重乳液通常是双纳米乳液,如油包水(O1/W/O2)纳米乳液,其中第一油相(O1)的纳米微滴悬浮在水相(W)中,并一起分散在第二油相(O2)中。双纳米乳液稳定,封装效率高,可模板化形成多相纳米粒子。多相纳米颗粒包括分散在连续基质中的 O1 相纳米微滴,该基质在室温和压力下可以是液体、凝胶或固体。制造双纳米乳剂的方法包括高能量力和连续纳米乳化。
