摘　　要：液体弹珠是由微小液滴与外部非润湿性松散颗粒组成的稳定的液固复合体。非润湿性颗粒的隔离作用不仅能有效隔绝内部微量液体与外部固体或液体基底的直接接触,还能通过给予多种外界刺激使其以滚动的形式实现微量液体的运输、降低表面的摩擦及提高液滴的操控性,在微量流体控制和微型化学/生物反应器方面具有广泛的应用前景。本文介绍了近年来国内外基于液体弹珠的微型反应器基础研究进展,综述了这类新兴微流体单元的基本性质、设计与制备的典型案例,并结合本文作者课题组在多刺激响应液体弹珠、液体中液体弹珠及其作为微型化学/生物反应器应用的研究工作,对该研究领域的问题和未来前景作了展望。Liquid marbles are liquid droplets encapsulated by hydrophobic particles at the liquid-gas interface.The non-wetting particles can not only effectively isolate the direct contact between the internal liquids and the external solid or liquid substrates,but also realize the transportation of miniature liquids in the form of rolling,reduce the friction on the surface and improve the controllability of droplets under multi-stimuli-responsive.The formation of liquid marbles triggered by multiple stimuli is desirable for their application in fields such as microfluidic transportation and miniature reactors for chemical/biological reactions.In this article,the recent research progresses on miniature reactors based on liquid marbles were summarized,including the designing approaches,constructions and applications.Current advances on remote control of liquid marbles using external stimuli and liquid marbles in liquid as a kind long-term and temperature-controlled miniature reactors were briefly introduced.Some insights into challenges and opportunities were also provided based on our own understanding of this field.
