The nanorobot

Robots are not only present at centimeter or millimeter scale, they are also present at nano scale!

Havard medical school in Boston developed cancer-killing nanorobots. The nanorobot is made of DNA and it seeks out for cancer cells in your body. After detecting a cancer cell it injects its payload of DNA-altering molecules,wherby the cancer is self-destruct.


It is called ‘nanorobot’ because it is capable of doing some robotic tasks. The robot has a barrel shape, each barrel is about 35 nanometers in diameter. It contains different sites at the inside for attaching some molecules. On the outer site it has two aptamers, short nucleotide strands with special sequences for recognizing molecules on the target cell. Once the correct target is reached, the aptamers spring open, to release the payload.

For an illustrated explanation of how nanorobots(in general) work, see the video below.

However, the nanorobots are not ready to enter the human body, because the researchers are not sure about how the robot itself will be cleaned after doing his tasks. If this kind of problems are solved, then it is possible that this kind of robots become real in therapeutics.

Now the researchers are beginning to thing to test such kind of robots on mice. Do you think that this is a good idea? Suppose that the mouse body react on a negative way on it, can they then sacrifice mice lives?

    It’s a good idea. I agree on testing in mice first. It’s quite hard to control these nanorobots after we put them into our body, we won’t know what will happen.

    I think nanorobots have a future. They will solve many problems. I also agree with the testing on mice first. I think this can be really useful.

    Like Sven said I do also think these robots have a broad future. Of coarse like in many biological sciences first animal testing should be done. And yes I agree with first test on mice, since many regulation are made for a good animal treatment. Only when first a range of in vitro experiments are done and the results seem favorable, the project is possibly accepted as an in vivo study. So when the nanorobot will be studied in mice, I am sure they are already quite convinced that it will work.

    I agree with all you guys. It would be scary if they a untested device in my body. I think it’s another way to kill cancer also.

    I my opinion, they should test this robots first on mice. After all it’s better to test them first on mice then on human beings.
