微功率控制声涡流提取微纳液滴
Micro/nanoliter droplet extraction by controlling acoustic vortex with miniwatt
摘要：
微/纳升液滴能够以微小的体积和显著的表面能实现多用途应用，这是比本体液体大的优点。然而，复杂的操纵和足够的权力之间的矛盾仍然是一个挑战。在这里，我们释放了我们的小功率抽吸器的潜力，在声学涡流束的帮助下抽吸液体并产生液滴，灵感来自螺旋对大多数生活在水中的软体动物来说意义重大的动力机制。这些液滴抽吸器通过来自螺旋电极换能器的具有轨道角动量的小辐射压力产生非常大的界面变形。在微米到纳米尺度上对物理、化学和生物物体进行精确的非接触式操纵，有望在微机器人、纳米反应器或纳米组装等领域取得巨大发展。
英文摘要：
Micro/nanoliter droplet is capable of achieving versatile applications with tiny volume and substantial surface energy, which is a big plus over bulk liquid. Yet, the contradiction of elaborate manipulation and enough power is still a challenge. Here, we unleash the potential of our miniwatt aspirators pumping up liquid and creating droplets with the help of acoustic vortex beams, inspired by the power mechanism that spirals are significant for most mollusks that live in water. These droplet aspirators produce very large interface deformations by small radiation pressures with orbit angular momentum from spiral-electrode transducers. The precisely contactless manipulation of physical, chemical and biological objects at micrometric down to nanometric scales, promises tremendous development in fields as diverse as microrobotics, nanoreactors, or nanoassemblies.
