SiNPs: silica nanoparticles; PEG-SiNPs: PEGylated-silica nanoparticles; Gen-PEG-SiHNM: genistein-PEGylated silica hybrid nanomaterials. Results are shown as mean ± standard error of four different batches analyzed by triplicate. Different letters (a, b, c, d) indicate statistical difference (P < 0.05) between samples.
