Magnetically driven carbon nanotubes for a highly efficient mechanical single cell damage.

Magnetized carbon nanotubes have previously been demonstrated as excellent candidates for the nanospearing transfection technique. In the presence of the moderate, spacially varying magnetic field, these magnetic nanorods exert motion, capable of piercing cell membranes, and allowing for highly efficient drug delivery. Here we study the possibility of enhancing this nanospearing technique, by varying magnetic strength and its time-space patterns, in order to inflict a highly efficient and selective, single cell mechanical damage.
