Cell response to single-walled carbon nanotubes in hybrid porous collagen sponges

- A new type of hybrid 3D porous SWCNTs/collagen sponges with controlled pore structures and nanoscaled topography was prepared.
- Improved cell proliferation and sGAG production of chondrocytes were obtained by the incorporation of SWCNTs.
- Interaction between cells and SWCNTs in 3D condition was disclosed.
