油包水滴的产生在生化反应、药物诊断和环境科学中具有越来越重要的作用。光流控技术是控制连续液相内介观粒子和液滴的有力工具。在这里,我们报道了一种基于微涡流芯片的灵活和小型化的液滴发生器,通过光热转换来熔化、捕获和释放不相容的载油中的皮升水滴。发生器中的液滴大小可以通过涡流的流速进行调节。进一步证明,生成的液滴可以通过可调的旋转轨迹实现对微观物质的尺寸选择性封装。结果表明,基于微涡的液滴发生器为液滴的稳定融合和包裹提供了一种位置和体积可控的方法。该系统将为液滴钳、微反应器、微混合器以及实际应用中的物体封装提供一个可控的微流控环境。
Water-in-oil droplet generation for object encapsulation is of increasing importance in biochemical reaction, drug diagnostics, and environmental science. Optofluidic technique is a powerful tool for manipulating mesoscopic particles and droplets within a continuous liquid phase. Here, we report a flexible and miniaturized droplet generator based on a microvortex chip by light-heat energy conversion to fuse, trap, and release picoliter aqueous droplets in the immiscible carrier oil. The droplet sizes in the generators can be tuned by the flow rate of the vortices. Further, it is demonstrated that the generated droplet can realize size-selective encapsulation of micro-matters with tunable rotating trajectories. The results showed that the microvortex-based droplet generator propose a method for the stable fusion and encapsulation of droplet with controllable positions and volumes. This system will provide a controllable microfluidic environment for droplet tweezers, micro-reactors, micro-mixers, and object encapsulation in practical applications.
