Abstract

 

“Lab-on-a-chip” microfluidic devices are in strong demand as alternative platforms to perform various bio-analytical experiments such as sensing and identification of single molecules, DNA analyses and sequencing, separation and purification of proteins, etc.  These microdevices not only provide enormous speed, resolution and efficiency in bioanalytical processes, but are also very cheap and convenient to use in both laboratory and field applications. These devices generally take advantages of different micro/nanoscale phenomena such as electroosmosis to pump liquids, and electrophoresis to separate objects of interest such as ions, proteins, DNA, bacteria, or cells from a mixture. In this presentation, a brief overview of microfluidic technology will be provided for a number of applications. Three specific unit operations will be demonstrated on microfluidic device for the development of a point of care cardiac biosensor. In the first example, transport, separation and concentration of proteins will be shown in microdevices using non-linear electrophoresis such as isotachophoresis and isoelectric focusing.  Next, local flow control in microchannels will be demonstrated using automated electric valves developed in our laboratory. Finally, sensing of different size and charge particles will be presented in a micro and nanofluidic device. Numerical results will also be shown in all cases for the device design and optimization.
