Publication number: 20150316529Abstract: The present invention relates to a system for analyzing molecular sequences, which is capable of decoding unit molecules constituting various biopolymers on a real-time basis using nanochannels. A control electrode serves to control the unit molecules passing along the channel such that the velocity of movement, arrangement, and directivity of the unit molecules can be rendered uniform. Particularly, at least four probe electrodes are separately formed in the case of decoding ss-DNA base molecules. Each probe electrode is coated with four different types of DNA base molecules to maximize detection efficiency through the interaction with complementary base molecules moving along the inside of the channel.Type: ApplicationFiled: April 25, 2012Publication date: November 5, 2015Applicant: Chung National University Industry-Academic Cooperation FoundationInventors: Jung Bum CHOI, Jong Jin LEE

Patent number: 9097719Abstract: The present system relates to a system architecture that uses a single electron transistor (SET) to analyze base sequences of deoxyribonucleic acid (DNA) at ultra high speed in real time. DNA represents the entire body of genetic information and consists of nucleotide units. There are a total of four types of nucleotides, and each nucleotide consists of an identical pentose (deoxyribose), phosphate group, and one of four types of bases (Adenine: A, Guanine: G, Cytosine: C, Thymine: T). A and G are purines having a bicyclic structure while C and T are pyrimidines having a monocyclic structure. Each has a different atomic arrangement, which signifies a different charge distribution from one another. Therefore, a system comprising a single electron transistor that is very sensitive to charges, a probe of a very small size that reacts to one nucleotide very effectively, and an extended gate that connects the SET with the probe, can be used to analyze DNA base sequences at ultra high speed in real time.Type: GrantFiled: October 8, 2009Date of Patent: August 4, 2015Assignee: NanoChips, Inc.Inventors: Jung Bum Choi, Jong Jin Lee
