BBC NEWS | Science/Nature | 'Nano-needle' operates on cell: "Scientists have performed a delicate surgical operation on a single living cell, using a needle that is just a few billionths of a metre wide.
They claim the procedure could be used to manipulate embryonic stem cells intended for use in medical treatment.
This 'nano-needle' was used together with an atomic force microscope (AFM) to penetrate the membrane of a cell to a depth of one or two micrometres."
