Figure 2From: NH2+ implantations induced superior hemocompatibility of carbon nanotubesTransmission spectra of MWCNTs and NH 2 /MWCNTs. (a) FTIR spectra of pristine MWCNTs and NH2/MWCNTs with 5 × 1014 and 1 × 1016 ions/cm2. C1s XPS spectra obtained from (b) pristine MWCNTs, (c) NH2/MWCNTs with 5 × 1014 ions/cm2, and (d) NH2/MWCNTs with 1 × 1016 ions/cm2.Back to article page
