World first: Nanobots traveled inside a living mouse to deliver medicine
posted January 21 2015 21:20.53 by Giorgos Lazaridis




It seems that the nanobot race is getting somewhere. Researchers in the University of California, San Diego, announced that they managed for the first time to let nanobots travel inside a living creature and deliver its medical payload.

These nanobots were tubular, approximately 20 micrometers long, 5 micrometers in diameter coated in zinc. They were released inside the stomach of a living mouse and they used gas bubbles (generated from the Zinc reacting with the hydrochloric acid) to propel themselves with the record speed of 60 micrometers per second. They headed towards the stomach lining where they embedded themselves, dissolved and delivered their payload (a nanoparticle compound) directly into the gut tissue. The test was 100% successful since all bots managed to deliver their payload. Moreover, they proved their robust nature since they remained attached to the lining for over 12 hours. The aftermath of this test showed no signs of raised toxicity levels or tissue damage. Let alone the fact that Zinc is a multipurpose nutrient.

It is sure that more and more researchers will contribute to generate human-targeted medicines and targeted medications. This is a quick glance to the near future. It is more than a small step. Thus far, no announcement has been made regarding human trials, but stay tuned...
