Manipulation of nanoparticles by AC electrothermal effect in laboratory-on-a-chip applications
摘要
Abstract
Microflow driven by AC electrothermal (ACET) effect is explored in order to seek new methods for pumping electrolytes with high conductivity fluid (more than 0. 02 S/m) at microscale. Based on the ACET theory, a physical model for particle trapping is established by a set of electrostatics, heat transfer and fluid dynamic equations. Further, fluid velocity fields are predicted using the software FEMLAB. Experiments are performed which verify the numerical results. The experimental results show that with appropriate electrode design, ACET effect can work on fluids with conductivity up to 1.53 S/m and trap particles at a low voltage.ACET devices can be readily integrated on chip into a microsystem. This offers insight into designing ACET lab-chips.关键词
