Abstract A polypyrrole‐graphene oxide (PPy/GO) nanocomposite was made chemically using a polymerization method in deep eutectic solvents up of choline chloride and propionic acid 1:2 molar ratio. The purpose this study is to examine the feasibility efficacy PPy/GO detection metronidazole pharmaceutical formulations utilizing spectrofluorometric techniques. Characterization synthesized conducted several methods such as transmission electron microscopy (TEM), scanning (SEM), Fourier‐transform infrared spectroscopy (FTIR), thermal gravimetric analysis (TGA), X‐ray diffraction (XRD). optimal parameters pH buffer solution, potential interferences, reaction duration, concentrations metronidazole, interference, test real sample were examined. Under established ideal conditions, curve calibration exhibited linear range 0.3–20 µg/mL, with correlation coefficient (R 2 ) 0.98712. limit (LOD) 0.09 while quantification (LOQ) 0.29 µg/mL. relative standard deviation (RSD) readings for five replicates three solutions (0.3, 10, or 20 µg/mL) assessed, yielding RSD percentages ranging from 1.29% 2.34% error −3.33% 1.20%, thereby demonstrating method's precision accuracy. This provides viable useful way detect samples. Moreover, data indicate that may constitute novel category fluorescence quenching reagent medicinal applications. approach effective regular quality control assays because its freedom interferences.
