U.S. scientists said they have succeeded in the development of self-propelled machine Nanonah able to attack the cancer cells inside the human body accurately.
The researchers reported in a study conducted under the supervision of Sean Douglas from the University of Harvard, MassachusettsAmerican, published Thursday in the journal "Science" that the U.S. This machine, developed along the lines used by the immune body itself consists of DNA folded and can be cooked in principle to become appropriate for the target cell.
However, the researchers pointed out at the same time that this machine has not been tested so far only in laboratory and farm it is not clear yet whether this machine will be used once within the human.
The researchers pointed out that there is a difference other research conducted experiments in this direction as well.
And machine-like hexagonal cage up 45 nanometers (a nanometer is one million mm) and thickness of 35 nanometers, which means that the thickness of less than two thousand times the thickness of the human head hair.
And consists of the cage which was attached using a technique called "DNA er origami" of two halves remain coherent by Latches especially made are similar to white blood cells, so that recognize target cells and landing on its surface, such as cancer cells, for example, shifts the latch as soon as landing machine on the cell and opens the cage with room for many of the active substances in this way up to the place of work.
The scientists during the experiment to download these machines self-propelled tanker molecular materials that will activate the characteristic self-suicide inside the cells, characteristic of those which are usually dysfunctional in cancer cells before they do these materials.
The scientists were able, through this method in vitro activation of characteristic self-destruction of cancer cells in the blood and lymph cells using carrier molecules for each of these cells separately.
The researchers explained that they were able to activate Similarly _khasasat multiple cells to be dealt with.
In the next step planned to researchers, who inspired the idea of studying the function of the human immune system try this technique on mice, "which will require a design the best for this machine is self-propelled, so as to ensure rotation, performance and function well in the circulation of mice," according to the researchers who have indicated they also the need to pressure the production costs of this machine.
