Abstract
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.
