Overview

Review highlights advances in nanomaterial-modified electrochemical sensors for food additive detection, suggesting scalable pathways toward real-time food safety monitoring.

Key Points

  • Review the development, analytical performance, and limitations of metal oxide, doped metal oxide, and carbon-based electrochemical sensors for identifying food additives.
  • Synthesized literature on electrochemical sensing platforms utilizing metal oxides, doped metal oxides, and carbon nanomaterials.
  • Evaluated performance characteristics across electroanalytical techniques including cyclic voltammetry (CV), differential pulse voltammetry (DPV), square wave voltammetry (SWV), and electrochemical impedance spectroscopy (EIS).
  • Doped metal oxides and carbon hybrid nanocomposites improve sensor performance via enhanced electron transfer kinetics, selectivity, and sensitivity.
  • Electrode fouling, poor long-term stability, and matrix interference remain primary operational challenges when analyzing complex food samples.
  • Integration of nanomaterial-based electrochemical sensors with Internet of Things (IoT) platforms offers a viable pathway for portable, real-time food monitoring systems.
