24. Chemical vapor deposition with iron nanoparticle catalysts(AP-MWNT); acid treated MWNTs (AT-MWNT); AT-MWNTs are functionalized (f-MWNTs); The short MWNTs (s-MWNTs) were prepared by annealing as-prepared short MWNT.

25. The f-MWNTs appear as highly debundled, individual nanotubes in the micrograph of the MWNT deposit layer (Figure 3a). This looser morphology of the f-MWNT coated filter contrasts sharply with the tightly bundled structure of the s-MWNT coated filter in Figure 3b. In this micrograph, we observe a strong sieving effect with no cell permeation into the MWNT deposit layer.

36. In conclusion, it was demonstrated the electrochemically controlled transport of water through nanotube membranes where a critical threshold voltage, which is strongly polarity dependent, is required to activate the water transport. The strong polarity dependence of the wetting suggests that oxygen-containing functional groups are attached as a result of water electrolysis at the nanotube anode, which causes the observed transition from nonwetting to wetting state. The controllable nanofluidic pumping that we demonstrate could have strong applications in biotechnology, lab-on-chip devices, and nanofluidic plumbing systems, which may be designed to controllably move and manipulate the flow of very small volumes of aqueous liquids precisely in space and time.
