I remember watching Fantastic Voyage as a kid and wondering if I would some day have tiny machines navigating through my bloodstream, repairing damage and keeping me healthy. Researchers at Penn State are working on it...
"A new spider-like micromachine could swim through a person's blood vessels, healing damaged areas and delivering drugs as it goes.
Ayusman Sen of Pennsylvania State University in University Park and his colleagues have created the self-propelling microspiders using spheres less than a micrometre wide. Each sphere is made up of two halves – one hemisphere is gold, the other silica – and looks like a gold-and-silver Christmas bauble."
