Electrochemical Sensor Technologies for Phenolic Analysis
Summary
Electrochemical sensor technologies exploit redox reactions at electrode interfaces to detect and quantify phenolic compounds, which are prevalent in environmental, industrial and biological contexts. Advances in electrode materials—such as nanostructured carbons, metal-organic frameworks and conducting polymers—have markedly improved sensitivity, selectivity and response time. Functionalisation strategies include molecular imprinting to confer target specificity and incorporation of redox mediators to lower overpotentials. Disposable screen-printed electrodes and flexible substrates facilitate low-cost, on-site analysis, while signal transduction methods like cyclic voltammetry and differential pulse voltammetry enable detection across submicromolar to millimolar ranges. Integration with microfluidic platforms and wireless data transmission supports real-time monitoring of water quality, pharmaceutical residues and food safety. Ongoing research aims to develop multi-analyte arrays, enhance anti-fouling properties and enable remote sensing to address global challenges in pollution control and healthcare diagnostics.

Recent studies have harnessed hybrid nanomaterials and biomimetic polymers to push the boundaries of phenolic sensing. A disposable screen-printed graphite electrode modified with molybdenum disulfide/nickel-metal-organic framework hybrid nanosheets achieved simultaneous detection of 4-aminophenol and acetaminophen over 0.1–600 μM, with a detection limit of 0.04 μM and excellent recovery in water and tablet samples. Flexible sensors based on laser-induced graphene electrodes functionalised with a multi-walled carbon nanotube–polyaniline composite exhibited enhanced electrocatalytic oxidation of 4-aminophenol, lowering the detection limit to 0.006 μM, maintaining stability over repeated cycles and enabling rapid field deployment. A chitosan-based molecularly imprinted polymer on a screen-printed carbon electrode provided high selectivity for p-aminophenol, delivering a linear response between 0.5 and 35 μM, a detection limit of 2.1 μM and robust performance against common interferents, illustrating the power of tailored recognition sites in complex matrices.
