Abstract (original English)

The promising perspectives of PLLA-based nanostructured biomaterials and their relevance in tissue engineering are reported. Nanocomposites based on PLLA and MWCNTs are developed with an MWCNT content ranging from 0 to 3 wt%. The electrical properties show a percolation threshold within a range of 0.21-0.33 wt% MWCNTs, and the conductivity increases by six orders of magnitude. The surface structure shows changes with the carbon nanotube concentration. The functional role of MWCNTs incorporation in terms of interactions with adult stem cells suggests that PLLA/MWCNT nanocomposites are suitable substrates for primary stem cell culture.
