Real-time bacterial capture and sorting using dielectrophoresis and electroosmosis

Simon S.X., Markewich H., Mallick E., Weber M., Fluid-Screen, Inc., US
Fluid-Screen, Inc. presents a bacterial capture and sorting method based on dielectrophoresis (DEP) and electroosmosis (EO). These electronic phenomena have been known to influence particle motion and capture since the 1960’s, however, technology based on [...]

High efficiency capture of multiple bacterial species by microfluidic dielectrophoresis filter

Simon S., Weber M., Fluid-Screen, Inc., US
Fluid-Screen, Inc. presents a bacterial concentration and filtration method based on dielectrophoresis (DEP). DEP has been known to induce particle motion since the 1960’s. However, yields and reproducibility have consistently been low in practice, reducing [...]

Negative Dielectrophoretic Force based High Efficiency and High Throughput Cell Sorting System Harnessing Paired Electrode Arrays and a Meso Size Channel

Lee D., Hwang B., Kim B., Korea Aerospace University, KR
Dielectrophoresis activated cell sorters (DACS), which exploit intrinsic dielectric properties of target cells, are highlighted as an alternative cell sorting method. Nonetheless, the DACS performing in micro channel have limitation with throughput while they accomplished [...]

Dual Helix Dielectrophoretic Cell Separator Fabricated Using the Direct-Write Spindle Deposition Technique

Guérin N., Lévesque M., Therriault D., École Polytechnique de Montréal, CA
Many biomedical procedures necessitating the separation of cells would benefit from the miniaturization of cell separators. This miniaturization effort has led to the development of 2D dielectrophoretic separators. The use of a 3D dielectrophoretic cell [...]

Fabrication of Microelectrodes on Polyester Membranes for Dielectrophoretic Cell Capture

Hanke C., Dittrich P.S., Reyes D.R., National Institute of Standards and Technology, US
We present a new system for cell capturing on porous polyester (PET) membranes using dielectrophoretic forces. For the first time gold microelectrodes were fabricated on PET membranes using conventional photolithographic techniques. Their characterization revealed no [...]

A Comparative Analysis of Transistors Based on Dielectrophoresis-Aligned Carbon Nanotubes (CNTs) and Assembled Random-Network CNTs

Juhala J.L., Griffith B.W., Duan Y., Xue W., Washington State University, US
CNTs have gained significant attention due to their potential as an alternative nanomaterial to be utilized in micro/nano-scale electronics. To continuously improve the performance of CNT-based electronic devices, the CNTs and their manipulation methods must [...]

Investigation of optimal separation condition in negative dielectrophoresis force based particle sorting platform

Lee J-H., Kim B-K., Kim Y.H., Kim B-K., Kim Y.H., Kim B-K., Kim Y.H., Korea Aerospace University, KR
we investigate an optimal separation condition regarding the gravitation, the hydrodynamic force and the n-DEP force acting on particles in the sorting platform since contribution of each force is the main parameter to determine SE. [...]

Parallel Fabrication of Single-Walled Carbon Nanotube based Piezoresistive Pressure Sensors

Burg B.R., Helbling T., Hierold C., Poulikakos D., ETH Zürich, CH
A major obstacle in the realization of commercially viable single-walled carbon nanotube (SWNT) based devices, hindering the functionality of this uniquely interesting type of material, is their type and site selective integration. In this work, [...]

A Novel Microscale Coulter Counter for Cell Monitoring and Detection

Wu Y., Critser J., Almasri M., University of Missouri, US
A MEMS based Coulter counter for cell detection and monitoring is designed, fabricated and characterized. The novelty of this design is the use of mixing, focusing and detection on a single chip as well as [...]
