  • Publication number: 20180135111
    Abstract: The present invention relates to a method and an apparatus for ultrasensitive quantitative analysis of a DNA biomarker, and more particularly, provides a method and a kit for quantitative analysis of target DNA using an atomic force microscope. The DNA quantification according to the present invention enables the quantification of target DNA at low concentration, which has been difficult to carry out by a conventional method, through adhesion force mapping by using an atomic force microscope, and does not result in DNA amplification and transformation nor require the use of a fluorescent marker. In particular, the method applies the size optimization of a probe DNA spot generated to capture target DNA, thereby enabling the quantitative analysis of ten or less target DNA molecules on various substrates.

  • Publication number: 20170276671
    Abstract: The present invention provides a regenerated cellulose membrane (RCM) that is useful in analysis of a sample for the presence of or the amount of a target molecule present in the sample. The invention also provides a method for producing and using the same. The RCM of the invention has a plurality of RCM functional groups on its surface in which a linker is covalently attached. The linker has a distal end and a proximal end, where the proximal end comprises at least one RCM linking functional group such that the RCM linking functional group is attached to the RCM functional group. The distal end of the linker comprises a receptor linking functional group that is used to covalently attach a receptor molecule. The receptor molecule is adapted for binding to a target molecule of interest when the target molecule is present in the sample. The RCM of the invention can be used for quantitative and/or qualitative analysis of a target molecule within the sample.

  • Patent number: 9087972
    Abstract: A flat panel display device and method of manufacturing the display device. The display device comprises a first substrate and a connection pad located along a side of the first substrate. A second substrate overlaps with the first substrate, wherein the second substrate does not overlap with an exposed portion of the first substrate. A first contact pad electrically couples the second substrate and the first substrate. A first distance from the side of the first substrate to a boundary between the exposed portion of the first substrate and the second substrate is greater than a second distance from the side of the first substrate to the first contact pad. The display device may be, for example, a touch capable display device that uses the first contact pad to transfer touch sensing signals from the second substrate to the first substrate.
