Rosette nanotubes make implants more biocompatible

Rosette nanotubes not only promise versatile components for advanced nanotechnology, but look likely to be useful in near-term nanomedicine as well. Jamie Dinkelacker brings to our attention the fact that Self-assembling 'nanotubes' offer promise for future artificial joints. These nanotubes are assembled from DNA base pair-like rosettes and have the virtue of being readily modified to have different chemical properties [see Customizable, Self-assembling Nanotubes]. Not only has it been demonstrated "that bone cells called osteoblasts attach better to nanotube-coated titanium than they do to conventional titanium used to make artificial joints," but the highly customizable nature of these nanotubes offers hope that coatings can be designed that are optimized for implants in different body parts.
