Integrating Sample Processing and Detection with Microchip Capillary Electrophoresis of DNA

Part of the Biotechnology Intelligence Unit book series (BIOIU)


DNA is the storage medium for inherited information in living systems and thus, techniques for nucleic acid analysis are of great importance. Integrated microchip instrumentation for rapid separation of DNA by capillary electrophoresis (CE) has emerged as an especially promising approach for assaying genetic material. Improvements in separation capabilities and sample capacity have made CE microdevices compatible with the rapid, high-throughput analysis needs in DNA studies. Perhaps the most critical advantage of adopting a microchip format for DNA characterization is the ability to couple sample handling operations, separation and miniaturized detection instrumentation seamlessly on a single device. Indeed, recent work with micromachined, portable PCR-CE systems indicates the exceptional promise of integrated DNA analysis microchips. Lastly, phase-changing sacrificial layer fabrication methods for polymer microdevices should lead to inexpensive, high-performance DNA characterization microchips. Continued progress in integrated microdevices for DNA analysis will enhance capabilities for medical, biological and forensic work.
