Glucose sensors using graphene-based materials. (A) Glucose responses to various graphene-based materials. (B) N-doped graphene having selectivity to glucose than uric acid and ascorbic acid. Figures (A,B) were reproduced from Wang et al. (2010) with permission from the American Chemical Society. (C) Schematic illustrations of the CVD graphene FET sensor. (D) Response curves of glucose in different gate voltages. Source–drain voltages are fixed to V_DS = −0.2 V. Figures (C,D) were reproduced from Kwak et al. (2012) with permission from Elsevier.
