DNA mutation detection and analysis using miniaturized microfluidic systems.

Identification of genetic sequence variations occurring on a population-wide scale is key to unraveling the complex interactions that are the underlying cause of many medical disorders and diseases. A critical need exists, however, for advanced technology to enable DNA mutation analysis to be performed with significantly higher throughput and at significantly lower cost than is currently attainable. Microfluidic systems offer an attractive platform to address these needs by combining the ability to perform rapid analysis with a simplified device format that can be inexpensively mass-produced. This paper will review recent progress toward developing these next-generation systems and discuss challenges associated with adapting these technologies for routine laboratory use.
