Amazing nano rockets in five easy steps (w/video)
(Nanowerk News) Jet engined nano size rockets, which contain a cargo may be a solution for several delivery jobs in the human body. And no, this is not science fiction, it is science. Nature Chemistry ("Autonomous movement of platinum-loaded stomatocytes") published the invention by chemists of the Institute for Molecules and Materials (IMM), Radboud University Nijmegen online on February 26. 'We think this is the first realistic and useable nano motor,' the researchers say.

Useable nano motor
Making a nano motor has been a dream of many researchers in the field. Several impressive attempts have been made, but at the end of the day they turned out to be too difficult to construct , had poor motor performance, or 'square' wheels.
'We work from a different angle and use nature as inspiration, but do not directly copy natural systems. In nature cells transport things all the time using motor systems,' says Prof. Jan van Hest. 'Our nano rocket is made building on a simple design, using so-called polymersomes , which are ball shaped containers, as the main component. Since we master the craft to include different types of molecules in these containers and link them to marker molecules or functional enzymes, and peptides on the outside, we foresee practical use of these engines in the near future, for instance as drug delivery systems.'
