Precision manipulation of various liquids is essential in many fields. Unlike solid objects, fluids are intrinsically divisible, enriching their fundamental operations with merging, dispensing, and splitting on top of moving. Fluids are sticky as well, calling for their lossless manipulation to prevent mass loss and contamination. We present photopyroelectric microfluidics that meet all the requirements. In response to the irradiation from even one single beam of light, our platform creates a unique wavy dielectrophoretic force field that is remarkably capable of performing desired loss-free (loss being 0.5% of existing one) manipulation of droplets of surface tension from 18.9 to 98.0 mN m⁻¹ and volume from 1 nl to 1000 μl, functioning as a “magic” wetting-proof hand to navigate, fuse, pinch, and cleave fluids on demand, enabling cargo carriers with droplet wheels and upgrading the limit of maximum concentration of deliverable protein by 4000-fold.

在许多领域，各种液体的精确处理至关重要。与固体物体不同，流体在本质上是可分割的，通过合并，分配和在移动时分裂来丰富其基本操作。流体也具有粘性，因此要求对其进行无损处理以防止质量损失和污染。我们提出了满足所有要求的光热电微流体。响应甚至来自单个光束的辐射，我们的平台创建了一个独特的波浪形介电泳力场，该场能出色地执行表面张力从18.9到18.9的液滴的所需无损（损失为现有的0.5％）的操纵。 98.0牛顿米^-1 体积从1 nl到1000μl，可充当“魔术”防潮手来按需导航，融合，挤压和裂解流体，使带有液滴轮的货物运输船将可递送蛋白质最大浓度的限制提高了4000倍-折。
