Abstract: Abstract:Multi-walled nanotubes (MWCNTs) were grown on carbonpapers by chemical vapor deposition (CVD). Adhesion and proliferation of L929 mouse fibroblasts and plateletson MWCNTs and carbon papers were investigated. The influence of different bloodprotein adsorption on the human skin fibroblasts growth was also studied. The resultsshowed that mouse fibroblasts implanted on MWCNTs tended to grow more prolificallythan those on carbon papers. The cell concentration observed on MWCNTsincreased from 1.25´105 /mL (cultured for 1 d) to 4.1´105/mL (culture for 7 d). No toxicity reaction was observed during the culturingperiod.By employing the adsorptionassay, it was found albumin, fibrinogen, and immunoglobulinG adhered on materials could promotethe adhesion and growth of the human skin fibroblasts. Furthermore, plateletadhesion rate on MWCNTs is lower than that on the carbon papers. These resultsindicate that MWCNTs have better tissue compatibility and blood compatibility.
