We used microfluidic technology for preparing gas–liquid Janus emulsions; we firstly proposed a one-step preparation method of micro-grippers and then characterized the function of oriented and precise delivery behavior. Because of the enrichment of Fe₃O₄ nanoparticles, the micro-gripper can reach a speed of 1.5 mm s⁻¹ driven by a magnetic field. The micro-gripper's body is made of a poly(N-isopropylacrylamide) hydrogel, a reversible temperature-responsive polymer. The thermo-sensitivity of hydrogels offers the function of grasping, to closely integrate with the target carried, ensuring the stability of the carrying process. The reversible variation of the hydrogel allows the micro-gripper to be reusable and have a long shelf life.

具有精确输送功能的柔性微爪的微流体制备†

我们使用微流体技术制备气液Janus乳液。我们首先提出了一种微夹爪的一步制备方法，然后表征了定向和精确输送行为的功能。由于Fe ₃ O ₄纳米颗粒的富集，微夹爪在磁场的驱动下可以达到1.5 mm s ^-1的速度。微型夹具的主体由可逆温度响应性聚合物聚N-异丙基丙烯酰胺水凝胶制成。水凝胶的热敏性具有抓握功能，可与所运载的目标紧密结合，从而确保了运载过程的稳定性。水凝胶的可逆变化使微型夹具可以重复使用，并具有较长的保存期限。
