Separation of submicron bioparticles by dielectrophoresis.
Submicron particles such as latex spheres and viruses can be manipulated and characterized using dielectrophoresis. By the use of appropriate microelectrode arrays, particles can be trapped or moved between regions of high or low electric fields. The magnitude and direction of the dielectrophoretic force on the particle depends on its dielectric properties, so that a heterogeneous mixture of pa...
متن کاملSeparation and Polarizability of Dna by Dielectrophoresis
Although separation of polymers based on the combination of dielectrophoretic trapping and electrophoretic forces has already been proposed 15 years ago [1], the experimental realization has only recently been demonstrated [2]. Here, we address the fast separation of biotechnologically relevant DNA by utilizing electrodeless dielectrophoresis in a simple, structured microfluidic chip. In additi...
متن کاملContinuous-flow particle separation by 3D Insulative dielectrophoresis using coherently shaped, dc-biased, ac electric fields.
We present the development of a continuous-flow, "dielectrophoretic spectrometer" based on insulative DEP techniques and three-dimensional geometric design. Hot-embossed thermoplastic devices allow for high-throughput analysis and geometric control of electric fields via ridged microstructures patterned in a high width-to-depth aspect ratio (250:1) channel. We manipulate particles with dc-biase...
متن کاملParticle Focusing and Separation through Lab-On-Chip Device by Dielectrophoresis
A Lab-On-Chip micro-device has been introduced for the focusing and separation of particles which exploits negative dielectrophoretic (nDEP) force. A 3D numerical computational model was presented to simulate the focusing and separation process. In particular, the model will solve for bioparticle movement and Joule heating. In the experimental study, the mixture of viable and nonviable yeast ce...
متن کاملBiological cell separation using dielectrophoresis
Basic IC fabrication techniques are employed in this paper with the purpose of designing a microfluidic device with a 3D electrode arrangement to separate live and dead biological cells. This is done using the concept of dielectrophoresis, which describes the transnational motion of particles due to the application of a non-uniform electrical field. The simulations where carried out using the p...
