Ultra-sensitive electrochemical sensing of acetaminophen and codeine in biological fluids using CuO/CuFe(2)O(4) nanoparticles as a novel electrocatalyst

Copper ferrite–copper oxide (CuO-CuFe(2)O(4)) nanoparticles as a semiconductor composite with p–n junction were synthesized by co-precipitation reaction. Then, a novel CuO-CuFe(2)O(4) carbon paste modified electrode was fabricated which displays an effectual electrocatalytic response to the oxidatio...

Sumario:Copper ferrite–copper oxide (CuO-CuFe(2)O(4)) nanoparticles as a semiconductor composite with p–n junction were synthesized by co-precipitation reaction. Then, a novel CuO-CuFe(2)O(4) carbon paste modified electrode was fabricated which displays an effectual electrocatalytic response to the oxidation of acetaminophen (AC) and codeine (CO). A linear range of 0.01–1.5 μmol L(−1) and 0.06–10.0 μmol L(−1) with the detection limits of 0.007 μmol L(−1) and 0.01 μmol L(−1) were achieved for AC and CO, respectively. The practical usage of the proposed sensor revealed reasonable results for quantification of AC and CO in biological fluids.
