Abstract
AbstractA facile, and novel construction strategy invented on electrochemical procedures for the assemblage of zinc oxide nanoparticles (ZnO NPs) with a multiwalled carbon nanotube modified carbon paste electrode (ZnO‐MWCNTMCPE) to ascertain the fluoroquinolone drug‐Moxifloxacin (MOX). The ZnO‐MWCNTMCPE can significantly improve the electron transfer process and lessen the impedance of the surface of the electrode. Besides, the oxidation of MOX has remarkably enhanced on the modified electrode. Under the optimal experimental conditions, the empirical results exhibited that the oxidation peak current was linearly proportional to the concentration of MOX in the range of 1.0×10−7 to 2.4×10−6 mol L−1 with a detection limit of 0.452×10−7 mol L−1. To analyze the practicality of the MOX determination technique in real samples, the intended sensor manipulated for the adjudication of MOX in human urine specimens, and the results authenticated the explore of MOX with the highest accuracy. Further, the proposed sensor system exercised for the simultaneous evaluation of paracetamol (ACOP) and MOX, the DPV technique unveiled the well‐separated peaks among ACOP (0.188 mV) and MOX (0.814 mV) with a peak separation (ΔE) of 626 mV in real samples. Therefore, the suggested system could sense and discover the MOX in the biological systems.
