They are widely used for the detection of various analytes, including heavy metals, biomolecules and pharmaceutical compounds. Since the electrochemical sensors can be easily modified with different materials to improve their sensitivity and selectivity, they offer advantages over other traditional analytical techniques. Among these modifiers, metal oxide nanoparticles are of particular importance due to their large surface area, catalytic activity and good electrochemical properties. Their incorporation into carbon electrodes improves detection limits, reproducibility and stability, making them very effective for advanced sensing applications.encarbon paste electrodeelectrochemical sensorsmetal oxide nanoparticleselectrochemical methodsconferenceObject
