AB  - A new coinage metal nanocluster surface molecularly imprinted polymethacrylic 
      acid nanoprobe (NC@MIP) for the selective determination of 2,4,6-trichlorophenol 
      (TCP) was prepared via microwave synthesis using 2,4,6-trichlorophenol as a 
      template molecule, copper nanoclusters (CuNC) as a nanosubstrate, and methacrylic 
      acid as a polymer monomer. It was found that the copper nanocluster MIP 
      (CuNC@MIP) shows the strongest catalytic performance for the reduction of 
      HAuCl(4) by hydrazine hydrate for the on-site generation of gold nanoparticles 
      (AuNPs) with the surface plasmon resonance (SPR) effects of resonance 
      surface-enhanced Raman scattering (SERS) and resonance Rayleigh scattering (RRS) 
      as well as absorption (Abs). When TCP was added, the CuNC@MIP nanoprobe and 
      TCP-formed CuNC@MIP-TCP nanoenzyme with stronger catalytic activity generated 
      more AuNPs, and the trimodal analytical signal was enhanced linearly. Therefore, 
      a new SERS/RRS/Abs trimodal sensing platform for TCP was constructed, which was 
      simple, rapid, sensitive, and selective. For each mode, the linear ranges were 
      0.0075-0.075, 0.010-0.10, and 0.010-0.10 nmol L(-1), and the detection limits 
      were 0.0010, 0.021, and 0.043 nmol L(-1), respectively. The relative deviation of 
      TCP in different water quality was 0.47%-2.5% and the recovery rate was 
      94.6%-108.6%.
