Abstract Droplet motion has been a long-standing interest in microfluidics as it is often limited by the high operating voltages, which hampers development of consumer applications. Forces generated liquid dielectrophoresis (L-DEP) can enhance surface wetting, without requiring chemical modification or texturing. This work presents droplet actuating platform to control wetting behaviour water d...

The dielectrophoresis (DEP) is suitable for handling micro-/nano-particles or tubes, sometimes together with gravity and/or flow of liquids. Recently research works on applications of DEP to biochemical measurement of biological cells alive or dead. Mass-processing of clinical laboratory test will be led to Clinical Laboratory Automation. We made discussions about what should be considered for ...

A chip with which to manipulate microparticles using wireless power transfer and pulse-driven dielectrophoresis has been designed and fabricated using a 0.18-μm CMOS process. The chip enables microparticle manipulation under a 0.7-V power supply and a 13-MHz clock, which are generated on the chip by means of an on-chip coil, a rectifier, and a Schmitt trigger circuit.

An innovative technique is proposed for the precise and scalable placement of 1D nanostructures in an affordable manner. This approach combines the dielectrophoresis phenomenon and capillary assembly to successfully align thousands of single nanowires at specific locations at the wafer. The nanowires are selectively trapped by taking advantage of the material--specific frequence dependence.

Continuous flow cell lysis by electroporation (EP), and cell and bead trapping by dielectrophoresis (DEP) have been demonstrated on a dielectrophoretic microfluidic chip. The results of lysing human white blood cells (WBC) and murine clonal cells (MN9D) by electroporation s a a m c ©

We demonstrate dynamic manipulation of microscopic particles using a DMDproduced projection image in an optoelectronics tweezers system. Single-particle trapping and movement (up to 40 μm/sec) via optically-induced dielectrophoresis were observed. 2003 Optical Society of America OCIS codes: (170.4520) Optical confinement and manipulation, (230.0250) Optoelectronics

Optoelectronic tweezers (OET) is a new tool for noninvasive, parallel manipulation of cells and/or micro/nanoparticles. Based on light-induced dielectrophoresis, OET can trap and sort colloidal particles, biological cells, nanowires and nanoparticles using a digital light projector. In this paper, we will present the principle and recent experimental results of OET. Keywords-Optoelectronic twee...
