An eco-friendly molecularly fluorescence composite structures based of carbon biomass based and their applications in chemical analysis

Abstract

As a result of the increase of anthropogenic and industrial components, different dangerous compounds for human health are constantly released into the environment in form of heavy metal ions and cancerogenic substances. The development of approaches for the detection of this substances is progressing well, but many of these methods have a number of disadvantages such as additional stages of analysis. A good alternative is a sensor based on luminescent carbon nanostructures (CNS).
CNS have been widely used in such industries as chemical analysis, imaging, nanomedicine, etc., due to their unique optical properties, high stability, biocompatibility, a wide range of organic raw materials and approaches for their synthesis.
Therefore, the purpose of our work was the developing approach to the synthesis of CNS with a controlled structure and functionality of the final product for the determination of heavy metal ions and cancerogenic substances. The approach is based on the principles of "green chemistry," simple, fast, but at the same time effective. Spherical calcium carbonate templates were selected to create a controlled structure. Various polysaccharides were taken as the carbon source.
Finally, obtained CNS were tested on actual water and sodium samples for analytical use.
The work was supported by project the Council for Grants of the President of the RussianFederation for the Support of Young Scientists, project no. MK-1759.2020.3.
