Medical industry is currently experimenting with lots of techniques to streamline healthcare. Some of these look like they were inspired by science-fiction literature. So it is with a recent experiment. Researchers employed tiny robot motors to crawl inside mice to deliver medicine at the exact point of their infections. The width of such autonomous vehicles is no longer than that of a human hair.
The Tiny Robot Motors Are Activated after They Enter in Contact with Gastric Acid
The University of California, San Diego allowed nanoengineer Joseph Wang and professor Liangfang Zhang from the Moores Cancer Center to run experiments with tiny robots. While their efficiency is low in the world of humans, they can render some impressive results in people’s internal system.
Therefore, the two experts started conducting trials on mice. The main goal of these tiny robot motors is to deliver drugs to where bacterial infections stemmed. Their material is made of a magnesium core. This choice was not random as this compound reacts with the gastric acid. Therefore, 20 minutes after they reached the stomach through swallowing, the micro motors are brought to life due to the reaction.
The way these minuscule vehicles can travel an internal system is by generating hydrogen bubbles. These propel the motors in the direction they need to reach their target. Once at the desired location, they can release the drugs. This way, scientists managed to avoid side effects of the medicine that can really take a toll on the livers. On top of that, the drug concentration remains strong which raises its efficiency considerably.
Mice Trials Rendered Amazing Success with No Side Effects and Faster Recovery
The experiment employed Helicobacter pylori as bacteria whereas the antibiotic consisted of clarithromycin. The mouse received five-day treatment. Scientists administered the medicine regularly through the same active transport system. However, they recorded zero side-effects of the drug.
After only 24 hours, the stomach recovered its normal PH level. More than this, the tiny robots are biodegradable. Therefore, there is no need for surgery to take them out. Instead, they start dissolving into the body without toxic residues.
