f-SWNTs with functional groups (-OH, -COOH, -NH2)
|
50-200 µg/mL |
S. aureus, B. Subtilis, and S. typhimurium
|
SWNTs functionalized with -OH and -COOH functional group showed more microbial inhibition rate (7-log reduction) against selected pathogens, while SWNTs with -NH2 displayed antimicrobial activity only at high concentrations.

|
| Silver-SWNTs functionalized with peptides (TP226, TP359, TP557) |
5 µg/mL |
S. aureus
|
The viability of bacteria increased by 4-log in non-treated skin model, whereas treated skin with functionalized silver-SWNTs showed antimicrobial activity only 1-log reduction. |
28
|
| Functionalized SWNTs with DNA and lysozyme (LSZ) |
~25 mg/L |
S. aureus, and M. lysodeikticus
|
Layer by layer coating of DNA- and LSZ-SWNTs displayed high antimicrobial activity (with 84% microbial reduction). |
29
|
| SWNTs incorporated inside poly(lactic-co-glycolic acid) |
< 2% by weight |
E. coli, and S. epidermidis
|
The metabolic activity of bacteria was considerably decreased (98%) with SWNTs-PLGA, while 15-20% reduction rate observed with pure PLGA. |

|
SWNTs-polyvinyl-N-carbazole (PVK) nanocomposite
|
3 wt.% |
E. coli, and B. subtilis
|
SWNTs-PVK nanocomposite induced a higher rate of bacterial inactivation (90% for B. subtilis and 94% for E. coli) in the planktonic cells and showed a significant reduction of biofilm formation.
|

|
| SWNTs assembled with poly(L-glutamic acid) (PGA) and poly(L-lysin)(PLL) (layer-by-layer) |
< 2% by weight |
E. coli, and S. epidermidis
|
SWNTs/PGA/PLL showed a higher rate of antimicrobial activity (90%) against selected pathogens than non-treated samples of PGA/PLL (with 20% reduction rate). |
26
|
| Oxidized SWNTs with poly(vinyl alcohol) (PVOH) nanocomposite |
0-10% (w/w) |
Pseudomonas aeruginosa
|
The viability of cell deposited on the surface of O-SWNTs-PVOH gradually decreased with increasing in nanotubes loading. |
49
|
| SWNTs/porphyrin composite |
0.04 mg/mL |
S. aureus
|
In the presence of visible light, SWNTs/porphyrin induced damage to the cell membrane. |

|
| Functionalized-SWNTs/ poly(ethylene glycol) (PEG) and poly(ε caprolactone) composites |
0.5-1.0 wt.% |
P. aeruginosa, and S. aureus
|
The proliferation of tested bacteria inhibited by f-SWNT/copolymer complex to a lower extent as compared to pure polymer complex. |
51
|
| SWNTs bound with polyamide membranes |
0.1-0.2 mg/mL |
E. coli
|
The complex of nanocomposite inactivated the microbial cells by 60% after 1 h of contact time. |
