Continuous flow reactors are recently being used for lab scale synthesis as well as pilot scale manufacturing of high value low volume chemicals. Here we present our work on a new configuration of flow reactor that includes several 1800 bends and yet a varying radius of curvature thereby ... Mehr lesen
Over the last decade, electrowetting-on-dielectric (EWOD) has become one of the most blistering and versatile tool in digital microfluidics. It enables control over fluid shape and flow by electrical signals alone, which is viable by effective utilization of the excess charge ... Mehr lesen
The Automotive industry has now become a technology of “Drive by Wire”. This technology is used to replace the conventional mechanical system by electromechanical system which is able to perform the same tasks faster, more reliably and accurately. The problems with the traditional ... Mehr lesen
Mixing is an important process in a microfluidic system such as micro total analysis systems. In this paper, design and analysis of various micro-mixers for enhancing the mixing performance is presented. At first, the basic principles of mixing along with the mixing length and mixing ... Mehr lesen
This paper presents the design and simulation of micromixer for Lab-On-Chip (LOC) applications. There are two types of micromixers: one is an active micromixer and another one is a passive micromixer. This paper investigates microfluidic flow characterization and mixing rate of two ... Mehr lesen
In this paper we present results of simulations done to predict the behavior of a system consisting of DNA molecules in an aqueous medium under the combined effect of AC Electroosmosis and Dielectrophoresis (DEP). ACEO is caused by the movement of fluid particles under the influence of ... Mehr lesen
Dielectrophoresis (or DEP) has been exploited for various micro and nano fluidics applications like patterning, sorting and separation. However, there are several commonly neglected issues in quantifying DEP forces. Such negligence could potentially lead to wrong DEP force predictions ... Mehr lesen
Dielectrophoresis is a phenomenon in which a force is exerted on a dielectric particle when it is subjected to a non-uniform electric field. In this research, we analyze dielectrophoretic (DEP) force using a geometry containing two electrodes, one with SiO2 and one without, with a gap ... Mehr lesen
Some types of rare pathogens can be detected and identified in human blood through a low-cost and label-free method. The On-Chip SESR identification process has a fast detection time (about 5 minutes) and a low detection limit. Discrimination of a species is done by sorting red blood ... Mehr lesen
In our experiments with manipulating cells with DEP, we noted that some cells are constantly spining. By hypothesing that the cell spining is caused by the non-circular shape of the cell body and the off-centered location of its nucleus and that the rotation direction depends on the ... Mehr lesen
