The increasing contamination of environmental media is a serious health issue requiring advanced methods to detect actual and emerging pollutants. In particular, high-sensitivity sensors for monitoring water pollutants are under deep investigation. Here, we review the synthesis, optical properties and applications of carbon dots for sensing contaminants in water samples. Fluorescence-based sensors have achieved ultrasensitive detection at nanomolar to picomolar concentrations. Carbon dot sensors have unique advantages such as biocompatibility, easy preparation, optical activity and wide applicability.
