Steroid skeleton-containing compound detection device and method for detecting steroid skeleton-containing compound using the same

摘要

A novel steroid skeleton-containing compound detection device and a steroid skeleton-containing compound detection method using the same are provided. The steroid skeleton-containing compound detection device of the present invention includes a transistor in which a nucleic acid sensor for detecting a steroid skeleton-containing compound is disposed. The nucleic acid sensor includes a three-dimensional formation region (D) that forms a predetermined three-dimensional structure and the steroid skeleton-containing device. A binding region (A) that binds to a compound, and in the absence of the steroid skeleton-containing compound, the stereogenic region (D) is inhibited from forming the steric structure, and in the presence of the steroid skeleton-containing compound, When the steroid skeleton-containing compound is brought into contact with the binding region (A), the steric formation region (D) forms the steric structure, and the steroid skeleton-containing compound is a solution containing an electrolyte when the steric structure is formed. The number of nucleotide residues constituting the nucleic acid sensor in the Debye length range of the solution Than during inhibition of the formation, wherein the increasing or decreasing.
