Precisely manipulating various liquids is essential in many fields and unlike solid objects, fluids are intrinsically divisible. Fluids are also sticky with appropriate functions for lossless manipulation to prevent loss and contamination. In a new report now published on Science Advances, Wei Li and colleagues in mechanical engineering and research and innovation in China presented photopyroelectric microfluidics to meet such diverse requirements. The fluidic platform facilitated the development of a unique wavy dielectrophoretic force field from a single beam of light to remarkably perform the desired loss-free manipulation of droplets and function as a “magic” wetting-proof surface. The liquid platform could navigate, fuse, pinch and cleave fluids on demand to establish cargo carriers with droplet wheels and has potential to upgrade the maximum concentration of deliverables such as protein by 4000-fold.
