3D Printed Microscopic Microfish to Swim Through Blood Delivering *****, Clean Up Toxins
http://www.medgadget.com/wp-content/uploads/2015/08/microscopic-fish.png
At the University of California, San Diego, researchers have 3D printed*tiny “microfish” that have propulsion mechanism, navigation, and even detoxification capabilities that may allow them to swim through blood and maybe even deliver targeted drug therapy. The hydrogel microfish are manufactured using*microscale continuous *optical printing (COP) which permits the creation of complicated shapes and multiple functional areas.
On the back of the microfish there’s a pouch with platinum na**particles that react with hydrogen peroxide to propel the fish forward, while on the front there’s a space filled with iron oxide na**particles that can be pulled on with a magnet to guide the fish in a particular direction.
The body of the fish was infused with*polydiacetylene (PDA) na**particles that are able to inactivate certain toxins. Interestingly, these na**particles emit a fluorescent glow when reacting with toxins, allowing their activity to be tracked and pointing to areas of high toxicity.
