Well‐aligned graphene oxide (GO) scrolls are prepared through the controlled folding/scrolling of single‐layer GO sheets using molecular combing on hydrophobic substrates, such as aged gold substrate, polydimethylsiloxane film, poly(L‐lactic acid) film, and octadecyltrimethoxysilane‐modified silicon dioxide. As a proof of concept, the gas sensor fabricated with a single reduced GO scroll is used to detect NO 2 gas with a concentration as low as 0.4 ppm.
