A facile and mild strategy to synthesize K-modified graphene using the room-temperature chemical modification of K in the graphene is demonstrated. The as-prepared K-modified graphene, used as an advanced electrode material, exhibits excellent electrocatalytic activity toward the oxidation of NO2 and is successfully applied in the determination of NO2 in vitro and from cancer cells.
