Fig. 3From: Systematic evaluation of oligodeoxynucleotide binding and hybridization to modified multi-walled carbon nanotubesInternalization of pristine and functionalized MWCNT by EJ28 cells as visualized by TEM. Representative TEM images of EJ28 cells after incubation with 0.1 mg/ml MWCNT for 24 h are depicted. Cells without MWCNT treatment served as control. Black arrows indicate MWCNT inside the cells.
