TEM images of SWCNTs entered into Arabidopsis mesophyll cells. a Some of the SWCNTs attached to the surface of cell wall, some crossed the membrane and located in the inner of cell membrane, mitochondria ①, nucleus ②, the inset is magnified image of SWCNTs inside the nucleus; B: SWCNTs located inside the vacuole; C: SWCNTs located in the vacuole ⑥ and chloroplast ⑦; D: aggregated SWCNTs located in the vacuole, ⑧⑨ ⑩ showed SWCNTs in different position.
