“…55 More recently, Zhao et al presented a nano-orice-based microuidic device using a DC-DEP method to continuously separate different types of micro and nanoparticles, which included 5.2 mm magnetic-coated PS beads, 7 mm uorescent PS beads, 14 mm sliver-coated hollow glass beads and 15 mm plain PS beads, with similar sizes by their different electric conductivities in a pressure-driven ow. 173 They also numerically demonstrated the separation of 5 mm Janus particles and homogeneous PS beads and the separation of 3 and 5 mm Janus particles using DC-DEP in the mode II, as shown in Fig. 8(d 3 ).…”

Insulator-based dielectrophoresis (iDEP), also known as electrodeless DEP, has become a well-known dielectrophoretic technique, no longer viewed as a new methodology. Significant advances on iDEP have been reported during the last 15 years. This review article aims to summarize some of the most important findings on iDEP organized by the type of dielectrophoretic mode: streaming and trapping iDEP. The former is primarily used for particle sorting, while the latter has great capability for particle enrichment. The characteristics of a wide array of devices are discussed for each type of dielectrophoretic mode in order to present an overview of the distinct designs and applications developed with iDEP. A short section on Joule heating effects and electrothermal flow is also included to highlight some of the challenges in the utilization of iDEP systems. The significant progress on iDEP illustrates its potential for a large number of applications, ranging from bioanalysis to clinical and biomedical assessments. The present article discusses the work on iDEP by numerous research groups around the world, with the aim of proving the reader with an overview of the state-of-the-art in iDEP microfluidic systems.

“…Unlike DC, 27 AC electric elds can be used to manipulate many types of particles in different media by simply adjusting AC parameters (i.e., magnitude, frequency, wave shape, wave symmetry and phase, etc. ), while eliminating the inuence of linear electrokinetic phenomenon including the traditional electrophoresis and electroosmosis.…”
