Introducing a Method for Green Synthesis of Carbon Nanoparticles and its Cytotoxicity

In recent years, synthesis of carbon dots from plant precursors has received great attention. In the present study, the green synthesis of carbon dots with two different methods and their cytotoxicity was compared. The size and morphological properties of carbon dots have been analyzed by facility of DLS, AFM, and TEM. Then cytotoxicity assay was performed. UV-Vis spectrum observed an absorption band at 250-280 nm suggesting the formation of carbon dots. Also, size and morphological properties of carbon dots were done. Despite the smaller size of the carbon dots in Teflon lined stainless-steel autoclave, both methods lacked significant cytotoxicity. Therefore, both methods have the necessary efficiency for different purposes due to their appropriate size and non-toxicity.
