▎ 摘　　要

NOVELTY - Single strand DNA sensor comprises a substrate, a first electrode (210) and a second electrode (220) formed on the substrate, a graphene pattern (100) connected to the first electrode and the second electrode and provided with a single-stranded DNA, which is a target, and a driving and detection unit, which provides a radio frequency (RF) frequency signal to the graphene pattern and detects a change in electrical properties for the RF frequency signal. USE - The sensor is useful for detecting single strand DNA as target. ADVANTAGE - The sensor does not require a label, is free from contamination, and can quickly perform an inspection in an accurate manner with high detection sensitivity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for producing the sensor involves (a) forming a first electrode and a second electrode on a substrate, (b) forming a graphene pattern to be electrically connected to the first electrode and the second electrode, and (c) connecting the first electrode and the second electrode to the GSG probe. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of single strand DNA sensor. 100Graphene pattern 210First electrode 220Second electrode
