SS THz induced NS uptake by PC 12 cells confirmed by CLSM and TEM. (a) Confocal micrographs displaying FITC NS uptake. The presence of NS near the membrane (white insets) is confirmed by the presence of the green signal (red arrows). Scale bars: 10 µm. (b) TEM micrographs displaying AuSi NS uptake (red arrows). NS appear to be localized inside the cytoplasm and closer to the cell membrane. Scale bars: 0.5 µm. |
