  • Patent number: 8182864
    Abstract: The present invention provides a method for modification of microchannels of a polydimethylsiloxane (PDMS) microchip, which includes the steps of: a) mixing an alkoxysilane precursor, an alkyl alkoxysilane precursor, and a solvent to prepare a sol-gel solution; b) oxidizing microchannels of the PDMS microchip; and c) coating the oxidized microchannels with the sol-gel solution prepared in step a). The PDMS microchip modified according to the method of the present invention shows higher hydrophilicity than an unmodified PDMS microchip. And, when the modified PDMS channels are filled with an organic solvent, channel swelling can be reduced, and thus various organic solvents can be used for the modified PDMS microchip compared to an unmodified PDMS microchip. Further, it can be widely applied for various fields because absorptivity of non-polar substances can be reduced.

  • Patent number: 7810932
    Abstract: Disclosed is a display device adapting a resolution improvement device capable of effectively improving a resolution in a projecting display device and a method thereof. A display device according to the present invention comprises: a light source; an image forming means for forming an image using a light emitted from the light source and an input image signal; a projection means for projecting an image formed in the image forming means on a screen; a displacement means for displacing an image displayed on the screen to be displaced; a driving means for driving the displacement to be moved; and an input signal applying means for applying an input signal to the driving means for the displacement means to be rotated in a predetermined direction. According to the present invention, different images are displayed on a screen periodically. It seems that the greater number of pixels is used than the real number in a sense of sight.

  • 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.

  • Patent number: 6810713
    Abstract: Various kinds of fluid can be handled and delivered accurately in infinitesimal amounts through microchannels formed in an elastic polymeric substrate by periodically squeezing selective portions of the microchannel using a rotor to apply an external force on the elastic substrate. The delivery rate of the fluid is in the range from pL/sec to mL/sec determined by the rotation speed of the rotor which presses the microchannels and the dimensions of the microchannel. Regardless of physical properties of the fluid to be delivered, various kinds of fluids can be accurately delivered through the microchannels in the desired amount.
