Stage IV. Assessment of the integration of plasma functionalization techniques and CNW for applications

 

Representative images obtained in the stage IV of the project TE_228

1. Perspectives on plasma processing of superhydrophobic CNW materials: superhydrophilic or superhydrophobic surfaces

Wettability control of CNW upon plasma treatment

 

2. Perspectives on plasma processing of metallic decorated CNW materials

Homogeneous dispersion of nanoparticles over the entire walls surface, after plasma treatment

 

3. Perspectives on plasma processing of CNW materials with cellular growth control

Pattern CNEW layers for proliferation/inhibition of cells attachment

 

- Cells adhesion on plasma treated CNWCs surface for cells culturing

a)	b)
a) The fibroblasts adhesion on patterning sample with CNWs as-deposited b) Images of fibroblasts attached on patterning sample with CNWs functionalized by nitrogen plasma

 

a)	b)
a) The adhesion of epithelial-like cells on patterning sample with CNWs as-deposited. b) Images of epithelia-like cells adhered on a patterning sample with CNWs functionalized by nitrogen plasma

The results of cellular viability assay indicated an increase on epithelial-like cells viability in the presence of CNWs functionalized.
