A team of International researchers invented micro-robots to diagnose and deliver drugs to areas of the human body that are hard to reach.
These micro-robots are built by coating a tiny algae with magnetic particles, that can smoothly swim in biological fluids such as the gastric fluid and diluted blood. These robots are about the size of a blood cell. They can be tracked in the hard-to-reach deeper tissues with the help of magnetic resonance imaging, and in the tissue close to the skin's surface by imaging the algae's natural luminescence. A study in the journal Science Robotics stated that these robots can also figure out the chemical changes linked to the onset of illnesses within various parts of the body.
Qi Zhou from the University of Edinburgh, said “A small-scale robot that can be remotely guided, is easily tracked and harmlessly biodegrades, potentially overcomes many of the challenges faced by minimally invasive therapies”. He further added, “We hope our discoveries will pave the way for the development of useful diagnostics or treatments”.
