Figure 2From: Novel pegylated silver coated carbon nanotubes kill Salmonella but they are non-toxic to eukaryotic cells FT-IR pattern of (a) SWCNTs-Ag. (b) pSWCNTs-Ag and PL-PEG. The characteristic peaks on PL-PEG and pSWCNTs-Ag such as alkane C-H, carbonyl c = o, hydroxyl O-H and methylene CH2 are indicated by arrows.Back to article page
