“…Chen and Shen proposed a new type of microscale particle removal filter as an alternative to electrostatic precipitators, cyclones, filters, Venturi scrubbers, foam precipitators, and other used in the particle removal industry [158]. A vertical microchannel, where airborne particles would deposit or sediment dielectrophoretically, could have advantages over traditional precipitators as lower energy consumption, no charging process requirement, compact volume, and enhanced removal efficiencies.…”

Dielectrophoresis (DEP) is the motion of polarizable particles in the presence of nonuniform electric fields. This novel electrokinetic technique has successfully been employed in many miniaturized systems for the manipulation and detection of microbes. This review article depicts the application of dielectrophoresis for the monitoring of microorganisms in microfluidic devices for environmental applications. The research studies described here are mainly conceived for water- and air-monitoring assessments, and are classified considering the target aimed to detect, concentrate, and/or separate, including chemical and toxicant agents, and microorganisms ranging from virus to protozoa. Dielectrophoresis has also played an important role in biofilm formation studies. This review article comprises mainly studies published from 2000 to present. Even in this relatively short time frame, there have been many significant contributions of this powerful and nascent technique related to environmental monitoring; thus, unveiling its great potential for future research directions.

“…It is also interesting to manipulate other kind of conductive particles including polymere, metal, viruses, DNA molecules or proteins according to [22]. Dielectrophoresis was also demonstrated to be useful to collect airborne particles for applications such as electret filters [23,24] or micro-electric precipitators [25]. Another use of the dielectrophoresis is presented by Wasisto et al [26] who designed a micro-cantilever type sensor using dielectrophoresis to increase the collection efficiency.…”
