Abstract Pickering emulsions based on biologically oriented compounds are highly appreciated in a variety of applications, such as food, cosmetics, and pharmaceuticals. Here, we develop the dual ultrasonic nebulizer spray method to efficiently produce alginate particles (APs) that can be used as eco-friendly and biocompatible Pickering stabilizers. This custom-designed method enables one-step preparation of chitosan-coated APs (CAPs) and direct encapsulation of magnetic nanoparticles within CAPs. The size of the resulting CAPs is about 5 μm in diameter, which is ideal for emulsion stabilizers. Unlike conventional APs production based on nozzle spraying, the developed method does not cause clogging problems, allowing large-scale production of APs-based Pickering stabilizers with a narrow size distribution. In addition, various CAPs-stabilized Pickering emulsions are demonstrated to be extremely stable against coalescence and drying upon exposure to air.

使用双超声雾化器喷雾法制备环保型藻酸盐基皮克林稳定剂

摘要 基于生物取向化合物的 Pickering 乳液在各种应用中受到高度赞赏，例如食品、化妆品和药物。在这里，我们开发了双超声雾化器喷雾方法，以高效生产可用作生态友好和生物相容性 Pickering 稳定剂的藻酸盐颗粒 (AP)。这种定制设计的方法可以一步制备壳聚糖包覆的 AP (CAP)，并将磁性纳米粒子直接封装在 CAP 中。所得 CAP 的尺寸约为直径 5 μm，非常适合用作乳液稳定剂。与基于喷嘴喷涂的传统 APs 生产不同，所开发的方法不会导致堵塞问题，允许大规模生产具有窄尺寸分布的 APs 基皮克林稳定剂。此外，
