Sensor Heavy Metal from Natural Resources for a Green Environment: A Review Relation Between Synthesis Method and Luminescence Properties of Carbon Dots
Abstract
Carbon dots are 10-nm nanomaterial classes as excellent candidates in various applications: physics, biology, chemistry, and food science due to high stable biocompatibility and high surface expansive. Carbon dots (CDs) produced from natural materials have received wide attention due to their unique benefits, easy availabilities, sufficient costs, and harmless to the ecosystem. The various properties of CDs can be obtained from various synthesis methods: hydrothermal, microwave-assisted, and pyrolysis. The CDs have shown enormous potential in metal particle detection, colorimetric sensors, electrochemical sensors, and pesticide sensor. This review provides systematic information on a synthesis method based on natural resources and the application to the environmental sensors for supporting the clean environment. We hopefully this review, useful as a reference source in providing the guidance or roadmap of new researchers to develop new strategy in increasing luminescence properties CDs for multi detection of heavy metal in the environment.
