A novel graphene oxide (GO) architecture is fabricated on hydrophilic-hydrophobic patterned alkanethiol self-assembled monolayers on Au by molecular combing of GO sheets. With hydrazine reduction, the reduced GO architecture-based device is demonstrated to detect NO2 gas. This simple method shows the potential to control the shape, orientation and position of GO sheets over large areas.
Keywords: graphene oxide; hydrophilic-hydrophobic micropatterns; microcontact printing; molecular combing; self-assembled monolayers.
