对基于连续型、时变型及与其他力场联用的三类介电电泳颗粒分离技术进行了综述。分析表明,连续型介电电泳的分离效果较好,但形式较为单一,一般为二元或顺序分离;时变型介电电泳则可以结合不同特点的分离形式,提高分离的选择性与灵活性;为了兼顾分离的通量、灵活性与分辨率等要求,与其他形式力场联用则是解决问题的有效途径之一。在此基础上,给出了介电电泳技术在分离问题中的几个研究方向,包括拓展至具有复杂结构的颗粒类型,与具体的生物和医学问题相结合向应用领域发展,以及与磁场等外加力场相结合等。
Three kinds of dielectrophoresis particle separation techniques based on continuous type, time variant and combined with other force fields are reviewed. The results show that the separation effect of continuous dielectrophoresis is better, but the form is simple, generally binary or sequential separation; time-variant dielectrophoresis can be combined with different forms of separation to improve separation selectivity and flexibility; In order to balance the requirements of flux, flexibility and resolution, the combination with other forms of force field is an effective way to solve the problem. Based on this, several research directions of dielectrophoresis in the separation problem are given, including extending to particle types with complex structure, combining with specific biological and medical problems to application fields, The combination of external force field.
