A new nanotube knife has been designed by researchers of the University of Colorado which would function in the same manner as that of a tight wire cheese slicer. If it turns out to be successful then it may be found in the hands of scientists studying cells and they would be able to cut them in a more accurate manner and study them.
Up till now scientists had to use those traditional knives which caused the samples to either bend or crack but the carbon nanotubes knives are quite strong and it is expected that these knives could even be used for making 3D cell images for electron tomography.
For making this knife, carbon nanotubes were welded between two electrochemically sharpened tungsten needles and this knife looks quite similar to a steel wire used for cutting cheese blocks.
