Abstract: 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 3D scaffold for cell culturing, as opposed to other scaffold systems where such an effect is not seen.
