[h=1]Fluorometric detection of influenza viral RNA using graphene oxide.[/h] Jeong S[SUP]1[/SUP], Kim DM[SUP]1[/SUP], An SY[SUP]2[/SUP], Kim DH[SUP]3[/SUP], Kim DE[SUP]4[/SUP].

[h=3]Abstract[/h] Simple and reliable detection of influenza viruses is important for timely prescription of antiviral therapy. Here, we developed a facile fluorometric system for detection of influenza subtype viral genes using graphene oxide (GO). A fluorescent DNA probe complementary to hemagglutinin gene of influenza virus is degraded by the 5' to 3' exonuclease activity of Taq polymerase during PCR. Upon addition of GO, the released fluorophore retains fluorescence without adsorption onto GO, whereas the intact fluorescent DNA probe is adsorbed onto GO with fluorescence quenching. Our multi well plate system can detect as low as 3.8 pg of influenza viral RNA.
