abstract = "We analyzed GFP cells after 24 h cultivated on superhydrophilic
vertically aligned carbon nanotube scaffolds. We produced two
different densities of VACNT scaffolds on Ti using Ni or Fe
catalysts. A simple and fast oxygen plasma treatment promoted the
superhydrophilicity of them. We used five different substrates,
such as: as-grown VACNT produced using Ni as catalyst (Ni),
as-grown VACNT produced using Fe as catalyst (Fe), VACNT-O
produced using Ni as catalyst (NiO), VACNT-O produced using Fe as
catalyst (FeO) and Ti (control). The
4\′,6-diamidino-2-phenylindole reagent nuclei stained the
adherent cells cultivated on five different analyzed scaffolds. We
used fluorescence microscopy for image collect, ImageJ® to count
adhered cell and GraphPad Prism 5® for statistical analysis. We
demonstrated in crescent order: Fe, Ni, NiO, FeO and Ti scaffolds
that had an improved cellular adhesion. Oxygen treatment
associated to high VACNT density (group FeO) presented
significantly superior cell adhesion up to 24 h. However, they do
not show significant differences compared with Ti substrates
(control). We demonstrated that all the analyzed substrates were
nontoxic. Also, we proposed that the density and hydrophilicity
influenced the cell adhesion behavior.",
