A. Cell viability (%) after 24 h of exposition to genistein (Gen), PEGylated silica nanoparticles (PEG-SiNPs), and genistein-PEGylated silica hybrid nanomaterials (Gen-PEG-SiHNM) determined by MTT assay. B. Lactate dehydrogenase (LDH) activity in HT29 cells after 24 h exposition with IC₅₀ of Gen, PEG-SiNPs and Gen-PEH-SiHNM. Each value represent the mean of three independent experiments by triplicate ± SE. *indicate significant difference in comparison with control by Dunnet’s test (P < 0.05).
