▎ 摘　　要

NOVELTY - Oxidized graphene fluorescent sensor (I) is new. USE - Oxidized graphene fluorescent sensor for use in double-stranded DNA testing field oxide including salmon sperm StDNA, herring sperm DNA and calf thymus DNA (all claimed). ADVANTAGE - The oxidized graphene fluorescent sensor ensures excellent molecule mutual action and strong fluorescence emission signal generation. DETAILED DESCRIPTION - Oxidized graphene fluorescent sensor of formula (I) is new. R=primary graphene oxide or secondary graphene oxide; n=6-12; and a and b=a natural number. An INDEPENDENT CLAIM is included for a method for preparing oxidized graphene fluorescent sensor. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic fluorescence emission spectrum of the oxidized graphene fluorescent sensor. (Drawing includes non-English language text).
