Nanotechnology: injections or sampling? New 'molecular syringes' under testing

Which is better, a quick vertical jab on the buttock or the delicately soft entry of a blood sample? Waiting to find out "for what," some are already wondering "how" to use those tiny "molecular syringes" which are carbon nanotubes. With a diameter of less than one millionth of a millimetre (nanometre) and a maximum length of just a few millimetres, the first use that springs to mind when we think of this ethereal tubes -- the smallest ever made by man -- is as potential needles for injecting drugs or genes into sick cells. And if a syringe it is, we had better start thinking about how to use them. Read More

The above picture is an illustration of how a nanorobot or a nanobot injects drug into a red blood cell and Phil Ball, a science writer warns in his column how pictures which are a combination of photographic reality and graphic inventions can persuade us into believing such things!
