From: Passage of Magnetic Tat-Conjugated Fe3O4@SiO2 Nanoparticles Across In Vitro Blood-Brain Barrier
Flow cytometry of U251 cells containing NPs. a Control group; Fe3O4@SiO2-Amino NPs, b in the absence of magnetic field, and c under magnetic explosion for 2 h; Fe3O4@SiO2-Tat NPs, d in the absence of magnetic field and e under magnetic explosion for 2 h. Higher intensity along the x axis indicates more FACS delivery, and percentage of cells with internalized NPs is indicated
