Özet

Nanomedicines have emerged as promising platforms for cancer therapy, with graphene quantum dots (GQDs) offering efficient drug delivery properties. In this study, mercaptoacetic acid-functionalized GQDs were synthesized and loaded with curcumin through π-π stacking interactions. Successful conjugation was confirmed by spectroscopic and microscopic analyses. The anticancer activity of curcumin-loaded GQDs (Cur-GQDs) was evaluated against triple-negative breast cancer (MDA-MB-231) cells using XTT cytotoxicity and migration assays. Cur-GQDs exhibited an IC₅₀ value of 66 µg/mL and significantly inhibited cell migration. Molecular docking further demonstrated strong binding affinities of Cur-GQDs toward VEGFA and BCL2 proteins, suggesting potential antiangiogenic and pro-apoptotic mechanisms. These findings indicate that Cur-GQDs represent a promising nanocarrier system for curcumin delivery in triple-negative breast cancer.
