Abstract

An extensive array of toxic chemicals is presently unconstrained into the environment in footings of airborne, aquatic, and solid wastes due to the swift international globalization and industrialization. Consequently, a sensitive, reliable, and cost-effective sensor platform for evolving environmental pollutants is of prodigious prominence. The significant encroachments obligate made on the effective electrochemical sensor platform centered on nanomaterials for environmental monitoring. Electrochemical sensors are currently extensively admitted as a sensitive exposure tool for disease diagnosis as well as the revealing of abundant species of pharmaceutical, clinical, industrial, food, and environmental origin. Nanomaterials have capable of impending to surge competitiveness of electrochemical sensors in environmental monitoring, though investigation has engrossed chiefly on advance of practice for devising new sensors, and the number of revisions for enhancing the enactment of sensors and the applicability to real samples is still inadequate. The substantial advance of the nanomaterials-based electrochemical sensor platforms is a bountiful rise to new push of generating novel technologies for securing the human and environmental safety. In the field of environmental monitoring, nanomaterials-based sensors exhibited great potentials in trace pollutants detection because nanomaterials possess large surface area, high surface reactivity, high catalytic efficiency, strong adsorption capacity. In this chapter, the recent trends in the development of the electrochemical sensor platforms-based nanomaterials such as metal nanoparticles, metal oxide nanomaterials, carbon nanomaterials, polymer, and biomaterials are considered.
