According to a new study published in the journal, Science Robotics, researchers have developed a swarm of nano-robots that can be magnetically controlled and could prove useful in performing specific, unique tasks like fighting cancer cells within the human body. The technology allows the scientists to simultaneously manipulate each member of the robotic army with pinpoint accuracy, something which remained a challenge until now.
Explaining the potential applications of these tiny robots, the researchers at Philips Innovative Technologies in Hamburg, Germany, said the magnetic swarms can be embedded in injectable microscopic pills, which would allow doctors to precisely target and damage the cancer tumors without affecting the healthy tissues, notes Live Science.
For a long time, scientists have toiled hard to design nano-robots that can travel down the bloodstream and eliminate only the harmful cells, writes Fusion. Recently, a team of Canadian researchers made a major breakthrough by engineering molecules that automate drug delivery, but the technology needs to stand the test of a human trial.
