(A) Relative amount of cells (%) in the extraction or supernatant of all the HeLa-GFP cells collected after the treatment by 40 μg/mL MNP_pY, MNP_Y, or MNP. (B) Relative amount of cells (%) in the extraction or supernatant of all the HS-5 cells collected after the treatment by 40 μg/mL MNP_pY. The bright field microscope images (×20 dry objective lens) of HeLa-GFP cells after treated with (C) MNP_pY and (D) MNP_Y show the interaction between cells and nanoparticles. Cells were incubated with the growth medium, Dulbecco’s Modified Eagle Medium, containing 40 μg/mL nanoparticles for 4 hrs. The initial number of cells is about 1.0×106 per 6 cm culture dish. The scale bar is 100 μm.
