Nanorobots Based On DNA Origami Technique Managed To Successfully Locate And Destroy Tumors In Lab Tests

It seems incredible but nanotechnology is evolving fast to truly amazing levels that could only be imagined as fantasy just 10 or 20 years ago. As cool as it sounds it’s not quite a surprise that the scientists developed the first nanorobots capable of locating and destroying tumors. Not nowadays with all the technology that surrounds us. In a new study published by researchers at the University of Arizona, the so-called DNA origami has already been successfully used.

This work has been able to develop nanorobots that can locate and destroy tumors

That is to say, this would be the first robotic system in the world of perfectly autonomous DNA, which would allow the design of precise drugs to be applied directly in cancer therapies. This technique could have fantastic applications in the fight against cancer and it could be used to fight against tumors with high precision and success rate.

The first demonstration has already taken place and has been very successful in lab mice affected by various cancers, such as melanoma, breast cancer, lung cancer, and ovarian cancer.

3 out of 8 mice have been successfully treated with this method which, according to scientists, is still perfectionated to work better.

The invention and development of these nanorobots have been made possible by DNA origami

This DNA origami technique shows the DNA and its ability to fold into other types of sizes and shapes at scales thousands of times smaller than the width of a human hair.

Nanorobots have been successful in destructing cancer cells without damaging other healthy ones as they can be programmed to transport molecules, as well as cause blockage of the tumor blood supply, preventing tissue death and shrinking various tumors.

Each of these nanorobots is a completely rectangular, flat, 90×60 nanometer DNA origami. An enzyme important for blood clotting, thrombin, is then attached to their surface.

In addition, each nanorobot is charged to focuses only on attacking the cancer cells.
