In this review we examine recent development and current status of electrochemical detection of organic micropullutants using electrochemical sensors and biosensors based on nanomaterials, and discuss the sensing principles of the nanomaterials modified electrodes in these sensors. Emphasis is given to the important effect of related nanomaterials on the detection of organic micropullutants. Finally, key challenges and opportunities on the directions toward future development are outlined.
