Carbon nanotubes as electrophysiological building blocks for a bioactive cell scaffold through biological assembly to induce osteogenesis.

Bio-functional cell scaffolds have great potential in the field of tissue regenerative medicine. In this work, a carbon nanotube (CNT) gel scaffold specific pairing of functionalized nucleobases was developed for specifically targeted drug delivery and osteogenesis. The CNT gel scaffold with nano-fibrous architectures was established by Watson-Crick base pairing between thymine and adenine of low molecular weight heparin, respectively.
