چکیده

Carbon dots have been found as a fluorescent material for many applications in the field of biology due to their desirable properties such as high fluorescence, water solubility, low toxicity, good biocompatibility, excellent optical properties, and high chemical stability. These include drug delivery applications, bioimaging, and diagnostic sensors. So far, many methods have been introduced, including arc discharge, laser erosion, and microwave heating to synthesize carbon dots. In the present study, pyrolysis and hydrothermal methods have been used for the green synthesis of fluorescent carbon dots. Among the advantages of this method are simplicity, cost-effectiveness, and no need for advanced laboratory equipment. Urtica dioica has been used as a precursor. For the synthesis of fluorescent carbon dots prepared by the pyrolysis method, precursor was heated to a specific temperature and time and the product was obtained as a powder.To prepare fluorescent carbon dots by hydrothermal method, pre-prepared material was used as raw material and deionized water was used as a solvent, the resulting solution was transferred to autoclave; Then the heating process was performed inside the oven at a specific temperature and time. The synthesized carbon dots were characterized by fluorescence spectroscopy (PL), dynamic light scattering (DLS), and fourier transform infrared spectroscopy (FTIR) techniques. The synthesized fluorescent carbon dots had good biocompatibility, emitted intense ultraviolet blue light, and could be used as fluorescence probes in imaging.
