Needle entering the cell nucleus

It is what the authors have called nanoneedles, Japanese researchers, and it is not for less, since it is 200 nanometers wide and 8 micrometers long travel. In short, they have sharpened the silicone tip of an atomic force microscope, using ionic rays.

With this needle it is said that molecules inside a cell can move from one place to another or introduce DNA filaments into the nucleus during gene therapy.
