Nanocomposites for Electrochemical Sensors

Nanocomposites modified electrodes as electrochemical sensors are becoming more important as they are cheap, possess high stability, selectivity, low limit of detection and portability for on-site detection. The analytical and quantitative detection of pollutants such as heavy metal ions, organic and inorganic contaminants in water resources in the environments and drugs in the human body require accurate, highly selective and sensitive techniques and modified electrodes incorporating nanocomposites as the sensing material is perfectly suited for this task. Nanocomposites are a combination of more than one type of material. It encompasses a wide range of materials such as ion conductors, insulators, polymers, two-dimensional materials, single metals and alloys, which may take forms such as nanoparticles, nanorods, nanofibers, nanotubes, nanosheets etc.

Nanocomposites can be modified according to the needs of electrochemical sensing. These needs encompass the selectivity and sensitivity towards the targeted analyte. The type of constituents of the nanocomposites affects the selectivity and sensitivity of detection. In addition, the electrochemical sensing mechanism hinges on the type of nanocomposite and elucidation of the electrochemical detection mechanism greatly improves the understanding of the type of nanocomposite best suited for a targeted analyte without interference from common interferent.
