Microscopic 'fish' could clean toxins from your bloodstream
Scientists are forever keen to get tiny robots working inside our bodies, despite pop culture warning us against the idea. Researchers from UC San Diego have joined the fray with a new idea: "microfish" robots that could one day "swim" through your bloodstream and cleanse toxins. The team devised a 3D-printing method called "microscale continuous optical printing," that let them create hundreds of fish-shaped bots thinner than a hair in just a few seconds. The printer is capable of creating custom shapes and adding nanoparticles that perform different functions, thanks to millions of micromirrors that project UV light onto photosensitive materials.
