New 3D-printed fish or micro robot is probably swimming around in your body

3D-printed fish

Scientists have been developed which may be microscopically small 3D-printed fish or micro robots which will swim around in the human body in the future.
Micro Robots have been around for a while. They are, for example, developed in view of the efficient use of medication. These micro robots may be applied in the future, in the body of patients after which they may release some drug in exactly the right place. But the micro robots that have been developed up to now are quite simple, and is not able to perform more complex tasks.
3D-printed fish
Researchers have therefore devised a new micro robot which can do this. It is a 3D-printed fish to 120 microns long and 30 microns thick (by comparison, a human hair is about 100 microns thick). The fish have platinum nano-particles in their tails. These particles react with hydrogen peroxide causing the fish to move. In the 'head' of the fish are magnetic nano-particles so that the fish can be controlled with a magnet.

"We have developed an entirely new method to create nature-inspired microscopic swimmers complex geometric structures that are also smaller than the width of a human hair," says scientists. "With this method, we can easily integrate multiple functions into these micro robots swimmers, so they can be used for numerous purposes."
Toxic substances cleanup
But what the fish can now do concretely?The researchers demonstrate that love. As they provided the fry of nano-particles that can neutralize toxins and then let them swim in a fluid containing toxic substances. Since the fish are powerful swimmers, they were able to neutralize many of the toxic substances. The researchers also made ​​sure that the fish went red light issue when the nano-particles in their body are bound to toxic molecules. Thus, they were able to monitor the purification process. "The beauty of this experiment is that it shows how to remove micro fish toxins and show that toxins are present," says scientist.

"Another exciting possibility that we can investigate is the application of drugs in the micro robots or 3D-printed fish" adds researcher . Fish can deliver drugs to particular part of the body.
