Description
Summary:This work explores the potential of carbon dots as a fluorescent probe in the determination of heavy ions and as an electrochemical biosensor. It also discusses how carbon dots can be introduced into the Fricke solution to potentially serve as an ionizing radiation sensor. The study presents a novel tissue equivalent dosimeter carbon dots‐based as an ionizing radiation sensor. The methodology for the synthesis of Nitrogen‐doped Carbon Dots N‐CDs and the characterization of the material are described. The results show that the N‐CDs have a high sensitivity to ionizing radiation and can be used as a dosimeter for radiation detection. The study also discusses the limitations and challenges of using carbon dots as a dosimeter for ionizing radiation. Overall, this study provides valuable insights into the potential applications of carbon dots in different fields and highlights the importance of further research in this area. The study describes the synthesis and characterization of carbon dots. These nanomaterials can be used as fluorescent sensors. Introduced in the Fricke solution, they detect ionizing radiation by oxidizing Fe2+ ions to Fe3+ ions. It has high sensitivity to gamma radiation, useful as a tissue‐equivalent dosimeter. Tested as radiation sensors, they showed two regions of linear response.
