  • Absorbance detection system for lab-on-a-chip
    Patent number: 7157053
    Abstract: A high-efficiency, high-sensitivity absorbance detection system in a lab-on-a-chip is provided. The absorbance detection system includes detection cells having an optical pathlength ten times and/or much longer than the width of a separation channel to improve detection sensitivity, lens structures for collimating light in the detection cells, and slit structures for preventing scattered light from entering detectors. The detection cells, the lens structures, and the slit structures of the absorbance detection system are fabricated and integrated in a lab-on-a-chip. The absorbance detection system exhibits excellent absorption efficiency, detection limit, and linearity, compared to existing absorbance detection systems, and can be applied for the detection of a variety of samples. The absorbance detection system does not need labeling of the samples which saves time and costs. The absorbance detection system can be used effectively in detecting trace compounds with a high sensitivity.

  • Assembly microchip using microfluidic breadboard
    Publication number: 20030012697
    Abstract: A microfluidic breadboard comprises a plurality of pairs of openings formed on an upper surface of a substrate and arranged at regular intervals, wherein each pair of openings are connected to each other through a microchannel formed in the bulk of the substrate so that the microfluidic breadboard has an array of U-shaped microchannels.
