Abstract: Due to their special features, quantum dots have recently attracted the attention of researchers in the fields of imaging, drug delivery, and cancer treatment. In this study, we prepared Ag2S quantum dots (QDs) intending to control the nucleus growth and reduce toxicity in Artemisia dracunculus (tarragon) extract substrate using the green synthesis method. Synthesized nanoparticles were analyzed using different characterization techniques. The DLS data analysis showed that Ag2S QDs prepared by the green synthesis method have a mean size of 56 nm, which is smaller compared to chemical synthesis. Additionally, the synthesis of Ag2S QDs with tarragon extract decreased the zeta potential from − 13 eV to -21 eV, which can be effective in enhancing colloidal stability and increasing their presence in the bloodstream. Examining the hemolysis data showed that the synthesis of Ag2S QDs with tarragon extract significantly reduces the lysis of red blood cells by modifying the surface chemistry. The cell culture data also confirmed the results of hemolysis, indicating increased cell viability with Ag2S QDs tarragon.
