Researchers have long dreamed of developing tiny robots that could roam about inside our bodies, delivering drugs with unprecedented precision, and hunting down and destroying cancer cells.

and when they injected them into the bloodstream of mice, the nanorobots could shrink tumors by blocking their blood supply.

The nanorobots were made from sheets of DNA rolled into tubes containing a blood-clotting drug. On the outside, the researchers placed a small DNA molecule that binds with a protein found only in tumors. When the bots reached tumors, this molecule attached to the protein, triggering the DNA tube to unroll and release the drug.

The researchers showed that the nanorobots only targeted the tumors and didn’t cause clotting elsewhere in the body. They say this offers a promising future of cancer treatments free of side effects.

What we call nanorobots are the next generation of nanomedicines because they give you much better control and can be made to work like a machine,

The idea of tiny disease-fighting machines working inside the human body can be traced at least as far back as the 1966 release of the movie “Fantastic Voyage,” in which a submarine and its crew were shrunk down and injected into a scientist’s body to remove a dangerous blood clot.

nanorobots loitering in our bloodstream could act as early warning systems for disease.
