Micro and nanoscale fluid mechanics transport in microfluidic devices pdf

Electrokinetic phenomena are a family of several different effects that occur in heterogeneous fluids, or in porous bodies micro and nanoscale fluid mechanics transport in microfluidic devices pdf with fluid, or in a fast flow over a flat surface. The term heterogeneous here means a fluid containing particles.

Various combinations of the driving force and moving phase determine various electrokinetic effects. There are detailed descriptions of electrokinetic phenomena in many books on interface and colloid science. Wikimedia Commons has media related to Electrokinetics.

This article is about the technology. This article needs additional citations for verification. Next to pressure sensors, airbag sensors and other mechanically movable structures, fluid handling devices were developed. The first LOC analysis system was a gas chromatograph, developed in 1979 by S.

A big boost in research and commercial interest came in the mid 1990s, when ┬ÁTAS technologies turned out to provide interesting tooling for genomics applications, like capillary electrophoresis and DNA microarrays. The basis for most LOC fabrication processes is photolithography. Initially most processes were in silicon, as these well-developed technologies were directly derived from semiconductor fabrication. LOCs may provide advantages, which are specific to their application.

The micro-manufacturing process required to make them is complex and labor intensive, requiring both expensive equipment and specialized personnel. In the microliter scale that LOCs deal with, surface dependent effects ike capillary forces, surface roughness or chemical interactions are more dominant. Lab-on-a-chip technology may soon become an important part of efforts to improve global health, particularly through the development of point-of-care testing devices. For the chips to be used in areas with limited resources, many challenges must be overcome. One active area of LOC research involves ways to diagnose and manage HIV infections.

3 million of these people receive anti, requiring both expensive equipment and specialized personnel. In the microliter scale that LOCs deal with – the basis for most LOC fabrication processes is photolithography. And Nanoscale Fluid Mechanics: Transport in Microfluidic Devices.

Around 40 million people are infected with HIV in the world today, yet only 1. 3 million of these people receive anti-retroviral treatment. HIV have never been tested for the disease. Lab-on-a-chip devices could be used to characterize pollen tube guidance in Arabidopsis thaliana. Specifically, plant on a chip is a miniaturized device in which pollen tissues and ovules could be incubated for plant sciences studies. Dielectrophoresis: detection of cancer cells and bacteria.
