Microfabricated DNA analysis system. Semi-annual report, August 1993--January 1994
We are miniaturizing instrumentation for the polymerase chain reaction (PCR) -- a bioanalytical technique that amplifies target sections of DNA through thermal cycling. This report focuses on delineating reaction chamber, design parameters through computer modeling and infrared imaging. We have also continued micro-chamber-based PCR experiments and have successfully amplified three different targets from two different biological sources. Specifically, we have amplified DNA from {beta}-globin (a subunit of hemoglobin), and two different-sized targets from the Human Immunodeficiency Virus (HIV). These experiments were performed in newly-designed chambers. Reaction chambers are also being designed with detection in mind, specifically for the detection of fluorescent DNA labels. Finally, some new developments in PCR technology are described as they represent potential biological diagnostics to be evaluated in microfabricated DNA analysis systems.
