Nanotubes help turn stem cells into cartilage

September 17, 2013

Researchers at the George Washington University in the US have employed carbon nanotubes to modify polymeric scaffolds, add nanoscale surface roughness to these structures, and modulate their mechanical properties. The idea is that these nanotubes can be incorporated into existing polymer networks so that the scaffolds’ properties match the characteristics of the human tissue extracellular matrix (ECM), which makes up cartilage.
