  • Patent number: 10112969
    Abstract: Embodiments relate to methods of sequencing nucleic acids. Embodiments encompass the use of nucleotide analogs and a nucleic acid polymerase enzyme or enzyme complex comprising proofreading activity. The nucleotide analogs may become incorporated into a replicating strand and induce the proofreading activity of the polymerizing enzyme, thereby prolonging the duration of a signal associated with nucleotide incorporation, resulting in more observable sequencing events and increasing the accuracy of nucleic acid sequencing.
    Type: Grant
    Filed: May 8, 2017
    Date of Patent: October 30, 2018
    Assignee: INDUSTRIAL TECHNOLOGY RESEARCH INSTITUTE
    Inventors: Chung-Fan Chiou, Chao-Chi Pan, Jenn-Yeh Fann, Shang-Chia Chang, Tsu-Ju Fu
  • Patent number: 10087207
    Abstract: This invention is to describe nucleotide analogs used in a method for the determination of a nucleic acid sequence. The method involves an enzyme, an enzyme complex or plural number of enzymes with more than one enzymatic activity and a set of nucleotide analogs, to achieve high signal readout accuracy in nucleic acid sequencing by making each signal to have a long signaling time span which allows a higher signal clarity.

  • Patent number: 7767441
    Abstract: A bioassay system is disclosed. The bioassay system may include a plurality of optical detection apparatuses, each of which includes a substrate having a light detector, and a linker site formed over the light detector, the linker site being treated to affix the biomolecule to the linker site. The linker site is proximate to the light detector and is spaced apart from the light detector by a distance of less than or equal to 100 micrometers. The light detector collects light emitted from the biomolecule within a solid angle of greater than or equal to 0.8 SI steridian. The optical detection apparatus may further include an excitation light source formed over the substrate so as to provide a light source for exciting a fluorophore attached to the biomolecule.
