英文摘要 | a novel fabrication process was presented to construct a monolithic integrated pcr-ce microfluidic dna analysis system as a step toward building a total genetic analysis microsystem. microfabricated titanium/platinum (ti/pt) heaters and resistance temperature detectors (rtds) were integrated on the backside of a bonded glass chip to provide good thermal transfer and precise temperature detection for the drilled pcr-wells. this heater/rtd integration procedure was simple and reliable, and the resulting metal layer can be easily renewed when the ti/pt layer was damaged in later use or novel heater/rtd design was desired. a straightforward "rtd-calibration" method was employed to optimize the chip-based thermal cycling conditions. this method was convenient and rapid, comparing with a conventional rtd-calibration/temperature adjustment method. the highest ramping rates of 14 degrees c/s for heating and 5 degrees c/s for cooling in a 3-mu l reaction volume allow 30 complete pcr cycles in about 33 min. after effectively passivating the pcr-well surface, successful lambda-phage dna amplifications were achieved using a two- or three-temperature cycling protocol. the functionality and performance of the integrated microsystem were demonstrated by successful amplification and subsequent on-line separation/sizing of lambda-phage dna. a rapid assay for hepatitis b virus, one of the major human pathogens, was performed in less than 45 min, demonstrating that the developed pcr-ce microsystem was capable of performing automatic and high-speed genetic analysis. |
