Abstract: The optical properties of quantum dots, preparation methods such as colloid synthesis, reverse micelle synthesis and sol-gel method, as well as their applications in the fields of ion sensors and organic small molecule sensors were reviewed. It is proposed that most quantum dot sensors are based on photoluminescence quenching, which is not accurate in practical application and hinders the sensor standardization. It is considered that the core-shell quantum dots can reduce the potential toxicity of some conventional core materials composed of heavy metals, and it is necessary to establish a standardized and systematic method to evaluate the safety of specific materials of quantum dots.

Keywords: quantum dot; nanomaterial; sensor
