3D collagen scaffolds coated with multiwalled carbon nanotubes: initial cell attachment to internal surface.
نویسندگان
چکیده
The cell adhesion in a multiwalled carbon nanotube-coated collagen sponge (MWCNT-coated sponge) was investigated. Immediately after seeding, the cells adhered to the inner surface of the MWCNT-coated sponge and a significantly larger number of cells were observed there than for a pure collagen sponge used as control. On the MWCNT-coated sponge, the cells appeared favorable adhesion and spread in the early stages in the center part of the sponge which cells rarely attached without MWCNT-coating. It was suggested that the physical structure of MWCNTs was effective for initial adhesion of cells from the result of serum-free culture. MWCNT-coating makes the material a suitable three-dimensional scaffold for cell culturing, as opposed to other scaffold systems where such an effect is not seen.

A fiber coating from polyaniline (PANI) was electrochemically prepared and employed for Solid phase micreoextraction (SPME). The PANI film was directly electrodeposited on the platinum wire surface using cyclic voltametry (CV) technique. The same method was applied for the preparation of SPME fiber coated by polyaniline multiwalled carbon nanotubes (PANI/MWCNTs) composite. The concentration of ...
