NanoNews: Nanoknives to cut cells

American researchers have built a carbon nanotube knife, finally showing that is not only possible to make this kind of material with plenty of medical applications, but one step closer to the atomic sharp edge knife that has even more potential.

American researchers have built a carbon nanotube knife. According to the National Institute of Standards and Technology (NIST), this nanoknife will be used to cut and study cells. With this new tool, scientists and biologists will be able to make 3D images of cells and tissues for electron tomography, which requires samples less than 300 nanometers thick. And as cells are usually stored in wax for dissection, the researchers plan to test their nanoknives on a block of wax later this year. But read more…
