The nanoscale approach allows the researchers to differentiate cancerous or pre-cancerous tissue from normal tissue, even if the specimens look identical under a normal biopsy. In both studies, the techniques worked regardless of age, tumor size, smoking history...Nanomedicine opens the way for nerve cell regeneration
...The graft material is composed entirely of aligned nanoscale polymer fibers. These polymer fibers act as physical guides for regenerating nerve fibers. They have also developed a way to make these aligned nanofibers bioactive by attaching various biochemicals directly onto the surfaces of the nanofibers.
