AB  - A new type of ratiometric molecularly imprinted fluorescence probe 
      (B-CQDs@Eu/MIPs) based on biomass carbon quantum dots (B-CQDs) and europium ions 
      (Eu(3+)) has been prepared to recognize and detect tetracycline (TC). In the 
      experiment, the fluorescent material B-CQDs were prepared using passion fruit 
      peels through microwave-assisted method, which by the meantime achieves the reuse 
      of biomass waste. TC can block the transition of some parts of electrons in the 
      prepared B-CQDs from the excited state to the ground state, resulting in the 
      weakening of its blue light (Ex = 394 nm, Em = 457 nm), while TC can be chelated 
      by Eu(3+) and emit red characteristic fluorescence (Ex = 394 nm, Em = 620 nm) due 
      to the antenna effect. Thus, a ratiometric fluorescence response to TC is the 
      result of the combined B-CQD and Eu(3+) . Based on this, we established the 
      ratiometric fluorescent molecularly imprinted (MIP) probe for the detection of 
      TC. The prepared B-CQDs@Eu/MIPs is aimed at catching the fluorescence changes of 
      target tetracycline (TC) sensitively with the special combination of the specific 
      recognition cavities and TC. The linear fluorescence quenching range of TC in 
      milk using the fluorescent probe was 25-2000 nM, and the detection limit was 
      7.9 nM. The recoveries of this method for TC were 94.2-103.7%, and the relative 
      standard deviations (RSDs) were 1.5-5.3%. Owing to the predetermined nature of 
      MIP technology and the special response of ratio fluorescence, the interference 
      of common substances is eliminated completely, which greatly improved the 
      selectivity of its practical applications.
