Science fiction no more — in an article out today in Nature Biotechnology, scientists were able to show tiny autonomous bots have the potential to function as intelligent delivery vehicles to cure cancer in mice.
Researchers at the École Polytechnique de Montréal used bacteria that follow magnetic pull to build a tiny pyramid:
By using a computer-controlled magnetic field, the researchers turned the bacteria into fully-compliant biological nanorobots.
The trick was using a type of microbe known as magnetotactic bacteria. These critters have little internal compasses, and will follow the pull of a magnetic field…
