Dielectrophoresis is the migration of an electrically polarizable particle in an inhomogeneous electric field. This migration can be exploited for several applications with (bio)molecules or cells. Dielectrophoresis is a noninvasive technique; therefore, it is very convenient for (selective) manipulation of (bio)molecules or cells. In this review, we will focus on DNA dielectrophoresis as this technique offers several advantages in trapping and immobilization, separation and purification, and analysis of DNA molecules. We present and discuss the underlying theory of the most important forces that have to be considered for applications with dielectrophoresis. Moreover, a review of DNA dielectrophoresis applications is provided to present the state-of-the-art and to offer the reader a perspective of the advances and current limitations of DNA dielectrophoresis.
介电泳是指可电极化颗粒在非均匀电场中的迁移。这种迁移可用于多种涉及(生物)分子或细胞的应用。介电泳是一种非侵入性技术;因此,它非常便于对(生物)分子或细胞进行(选择性)操控。在本综述中,我们将重点关注DNA介电泳,因为该技术在DNA分子的捕获与固定、分离与纯化以及分析方面具有诸多优势。我们将阐述并讨论介电泳应用中必须考虑的最重要作用力的基础理论。此外,还将对DNA介电泳的应用进行综述,以展现其当前水平,并让读者了解DNA介电泳的进展及当前存在的局限性。
