微流控光学芯片具有微型化、集成化、可调化的优势,其应用中常碰到的技术瓶颈是液体驱动技术。微量液体具有与大块液体不同的性质,利用其微观特性可发展新型液体驱动技术,该技术有利于微流控光学芯片的微型化、集成化及使用的灵活性。阐述了几种利用表面张力、热蒸汽、光压、Marangoni对流、磁场以及液体与电磁相互作用等驱动微液体的新型技术。

Optofluidics chips have the advantages of miniaturization,integration,and reconfigurability.The technique on actuation of liquid often becomes the bottleneck in the research of optofluidics.The property of minim liquid is different from that of bulk liquid,so new techniques on actuation of liquid using microcosmic characteristics are researched.They are more miniaturizing,integrating and flexible than the macro-techniques.Some new techniques by using surface tension,heat,radiation pressure,Marangoni convection,magnetic field,and the interaction between liquid and electromagnetism on actuation of liquid of optofluidic chips are described.
