Scholarcy highlights

  • Graphene oxide nanoribbons have been prepared by chemically unzipping multiwalled carbon nanotubes
  • Raman spectroscopy and X-ray photoelectron spectroscopy characterizations indicate that the thermal reduction in the presence of ethanol vapor effectively restores the graphitic structure of the GONR as compared to chemical reduction with hydrazine vapor
  • Electrical measurements under a liquid-gate configuration demonstrates that reduced graphene oxide nanoribbons network field-effect transistors exhibit much higher on/off ratios than a network of microsized reduced graphene oxides or a continuous film of single-layered pristine or chemical vapor deposited graphene
  • We demonstrated the potential applications of rGONR networks for biosensing, the real-time and sensitive detection of adenosine triphosphate molecules
  • A graphenenanoribbon network and its biosensing application
