许多化学和生物过程涉及相分离;然而，控制这是具有挑战性的。在这里，我们展示了局部相分离，使用光镊在热响应离子液体/水溶液。在近红外激光照射时，在焦点处形成单个液滴。液滴具有由高度浓缩的离子液体组成的核心。从光学势和热势的空间分布角度讨论了核壳液滴的形成机理。
Many chemical and biological processes involve phase separation; however, controlling this is challenging. Here, we demonstrate local phase separation using optical tweezers in a thermo-responsive ionic liquid/water solution. Upon near-infrared laser irradiation, a single droplet is formed at the focal spot. The droplet has a core consisting of highly concentrated ionic liquid. The mechanism of the core–shell droplet formation is discussed in view of the spatial distribution of optical and thermal potentials.
