      Detection of Ractopamine in Pork Liver.

AB  - Many countries have allowed farmers to feed beta-adrenergic receptor agonists, such 
      as ractopamine (Rac), to animals to improve the quality of their meat. However, 
      Rac consumption can cause health problems for humans; thus, detecting Rac in meat 
      before its packaging is essential. Consequently, this study developed a simple 
      and sensitive electrochemical sensor by modifying a glassy carbon electrode (GCE) 
      with Nafion/silver nanoparticles (Nafion/AgNPs). When this electrochemical sensor 
      is used to detect Rac, electrostatic interaction occurs between Nafion and Rac, 
      and the AgNPs oxidize Rac; thus, the accumulation and electrochemical sensing of 
      Rac are achieved. Differential pulse voltammetry indicated that the as-prepared 
      Nafion/AgNP-GCE sensor exhibited suitable electrochemical sensing ability under 
      optimum conditions (6.0 muL of 0.10% Nafion/AgNPs in a Britton-Robertson buffer 
      solution with a pH of 1.8, an accumulation potential of -0.2 V, and a Rac 
      accumulation duration of 300 s). Moreover, this sensor has an extremely low limit 
      of detection and high sensitivity (1.60 x 10(-3) ppm and 2.14 muA/ppm, 
      respectively) in the Rac concentration range 7.50 x 10(-3)-1.00 ppm. The 
      as-prepared sensor also exhibits satisfactory reproducibility and storage 
      stability, with the corresponding relative standard deviations (RSDs) being 4.27% 
      (n = 5) and 1.56% (n = 10), respectively. The proposed electrochemical sensor was 
      successfully used to determine the Rac content in pig liver samples, with spiked 
      recoveries of 95.2-101.8% and RSDs of 0.55-4.83% being achieved.
