Glimpses Of The Future

“Fantastic Voyage” Becomes Science Fact With Robots That Swim In Your Blood

Delivering chemotherapy drugs directly to cancers could help reduce side effects, and soon that job could be done by tiny 3D-printed robotic animals – just like in the 1960s sci-fi pic “Fantastic Voyage”. These microrobots are steered by magnets, and only release their drug payload when they encounter the acidic environment around a tumour.

The new microrobots are made of hydrogel 3D printed in the shape of different animals, like a fish, a crab and a butterfly, with voids that can carry particles. The development team adjusted the printing density in specific areas, like the edges of the crab’s claws or the fish’s mouth, so that they can open or close in response to changes in acidity. Finally, the microrobots were placed in a solution containing iron oxide nanoparticles to make them magnetic.

The result was microrobots that could be loaded up with drug nanoparticles and steered towards a target location using magnets, where they would release their payload automatically due to changes in pH levels.
