▎ 摘　　要

NOVELTY - Nanographene-sensor or diagnostic kit comprises a graphene containing a nuclear transition signal, and a probe containing a fluorescent substance. USE - Nanographene-sensor or diagnostic kit for detecting a nucleic acid in a nuclear nucleus, for diagnosing the neurodegenerative disease by using probe, Where neurodegenerative disease is selected from a group consist of Parkinson's disease, Alzheimer's disease, Huntington's disease, amyotrophic lateral sclerosis and multiple sclerosis, for diagnosing the nerve development failure (all claimed). ADVANTAGE - The nanographene-sensor or diagnostic kit provides high reliability and resolution results, carries out detection in simple, rapid and accurate manner in living tissue or cell, easily observes inhibitory effect of nucleic acid in the nucleus in treating small interfering RNA, and helps to determine a rapid treatment policy. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for detecting nucleic acid in a nuclear nucleus, which involves mixing a sample with the nanographene sensor or the diagnostic kit.
