According to Jacobs School of Engineering website, nanoengineers at the University of California, San Diego 3D printed multipurpose fish-shaped microrobots — called microfish. They were made to swim around efficiently in liquids, are chemically powered by hydrogen peroxide and can be controlled magnetically. These synthetic microfish could allow for detoxification and drug delivery inside the body.
So imagine a group of your own 3D printed superheroes being inserted into your body to feed on toxins and deliver drugs to specific sites. How cool would that be? I’m imagining science-fiction-like scenes where these mcirofish decide to go rogue and start feeding on healthy human organ cells. Would a SWAT team of microfish be sent in to fetch them, or would surgery be done to get them out by force. Coming to think about it? What are the dangers of having such foreign objects roaming around in the human body? But then again, if patients are willing to put radioactive tracers in their bodies for diagnosing internal bleeding or problems with the thyroid gland, then a school of fish feeding on toxins might not be that bad.
I can’t wait to see the future application of this research.
