Fe-doping-driven enhancement of electronic conductivity and electrocatalytic performance in Gd₂O₃ nanoparticles for ultrasensitive electrochemical detection of chloramphenicol in pharmaceutical and milk samples.

ABSTRACT: In this study, Gd₂O₃ and Fe-doped Gd₂O₃ NPs were synthesized via a thermal decomposition method and integrated into an electrochemical sensing platform to systematically investigate the impact of Fe doping on the electronic conductivity and electrocatalytic performance toward sensitive chloramphenicol (CAP) detection. The structural, morphological, and compositional properties of the Gd₂O₃ and Fe-doped Gd₂O₃ NPs were characterized using FE-SEM, TEM, and VSM techniques. Fe doping significantly enhances the electrical conductivity and the electrochemically active surface area, which was confirmed by cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS) measurements.
