Figure 2. Representative TEM images of drug loaded nanotubes.
Electron micrographs of (A) DSPE-mPEG coated MWCNT, (B–D) P3A1-MWCNT[1], and (E–F) P3A1-MWCNT[2] (scale bar = 100 nm) are shown. WHITE ARROWs indicate some areas of electron dense platinum (P3A1) bound to MWCNTs. BLACK ARROWs indicate aggregates of P3A1 and DSPE-mPEG not bound to MWCNTs. (G) A schematic summarizing the preparation and structures of the P3A1 nanoparticles is shown.
