AB  - A high-efficiency spectrophotometric method based on nitrogen-doped fluorescent 
      carbon dots (N-FCDs) was developed for the ultrasensitive determination of 
      carmine (CRM) in foodstuffs. The N-FCDs were fabricated via a one-pot 
      hydrothermal method with m-phenylenediamine as the starting material. The 
      detection principle was based on the fluorescence quenching effect of N-FCDs by 
      CRM, where their interaction was due to the inner filter effect (IFE) and static 
      quenching. A good linear relationship was established for CRM detection in a 
      concentration range of 0.1-10.0 muM with a detection limit as low as 11.2 nM. The 
      proposed method achieved satisfactory results for CRM determination in commercial 
      food products with recoveries better than 98.6% and relative standard deviations 
      (RSDs) less than 4.07%. The method established in this study was simple, 
      ultrasensitive and reliable for rapid detecting CRM in a food matrix, which could 
      be potentially used as a useful sensing agent for the analysis of additive food 
      colourants.
