Fig. 1From: Curcumin-enriched Gemini surfactant nanoparticles exhibited tumoricidal effects on human 3D spheroid HT-29 cells in vitroFTIR analysis (a), SEM imaging (b), and uptake of Gemini-Cur NPs after 6 h (c). A subcellular accumulation of Gemini-Cur NPs was found in human colorectal adenocarcinoma HT-29 cells compared to the group incubated with the Cur aloneBack to article page
