abstract = "Sensing of acetone using the quantum capacitance in graphene is demonstrated. The sensor was constructed by using graphene as the top electrode in a metal-oxide-graphene variable capacitor (varactor) structure. The relative capacitance change was found to vary with acetone concentration with a relative capacitance sensitivity, ΔC/C of 1.29 ± 0.04 × 10-4 % / ppmv. The sensor was also found to have 3x enhanced sensitivity in dry air compared to N2 and showed excellent reversibility. The results represent the first step toward the realization of passive, wireless acetone sensors using graphene varactors.",
