Green fluorescent silver (Ag)‐doped graphite carbon nitride (Ag‐g‐C 3 N 4 ) nanosheets have been fabricated by an ultrasonic exfoliating method. The fluorescence of the Ag‐g‐C 3 N 4 nanosheets is quenched by curcumin. The fluorescence intensity decreases with the increase in the concentration of curcumin, indicating that the Ag‐g‐C 3 N 4 nanosheets can function as a non‐toxic and facile fluorescence probe to detect curcumin. The fluorescence intensity of Ag‐g‐C 3 N 4 nanosheets shows a linear relationship to curcumin in the concentration range 0.01–2.00 μM with a low detection limit of 38 nM. The fluorescence quenching process between curcumin and Ag‐g‐C 3 N 4 nanosheets mainly is based on static quenching. The fluorescent probe has been successfully applied to analyse curcumin in human urine and serum samples with satisfactory results.
