Researchers at the University of California, San Diego successfully treated bacterial gastric infections in mice using micro-motors.

The use of nano-technology in medicine isn’t new but this is the first time chemical treatments have been administered in vivo with this kind of technology.

Again, Nano-Technology in medicine

In the not-so-distant future, drug treatments could be delivered straight to the problem area with the help of Nano-Technology. 

The micro-motors used measured just half the width of a human hair. Loaded with a clinical dose of antibiotics, they traveled through the stomach, neutralizing gastric acid and successfully distributing the drugs.

Traditionally, drugs to treat ulcers and stomach diseases are taken orally. This can cause problems because drugs are often acid-sensitive and can be destroyed by the stomach’s gastric acid.

To stop this from happening, doctors prescribe proton pump inhibitors to take with the treatment. They suppress gastric acid production so that the drugs can do their job.

But proton pump inhibitors cause another problem. They come with a long list of nasty side effects, including headaches, diarrhea, and fatigue. In the worst instances, they can trigger depression or anxiety and (in very rare cases) death.

Micro-motors Help Cure Stomach

The great thing about these micro-motors is that they are able to neutralize gastric acid without the use of proton pump inhibitors. This all comes down to the way they’re built.

The micro-motors used in the experiment were made from a magnesium core, layers of antibiotics (clarithromycin) and a positively charged polymer that helps them stick to the stomach wall.

The magnesium reacts with the gastric acid in the stomach to propel it with a stream of hydrogen bubbles. This reaction also has the convenient side effect of reducing the amount of stomach acid. It’s only temporary and the stomach pH returns to normal within 24 hours.

Researchers administered these micro-motors to mice with stomach infections caused by the Helicobacter pylori bacteria, a bacteria found in roughly half the global population.

They did this for five days in a row. After the experiment, they examined the bacterial count in the mice’s stomachs. The results showed the micrometers were as successful in treating the infection as oral medication – without the side effects.

The future is so close

It’s still early stages but the researchers have already started planning future trials to delve deeper into the possibilities of this nano-technology.  “This work opens the door to the use of synthetic motors as an active-delivery platform for in vivo treatment of diseases, and will likely trigger intensive research interests in this area,” the study authors write.

The results are extremely promising and it might not be too long before they become common procedure, not just for gastric infections but for all sorts of medical complaints.
