Holy Fantastic Voyage, Batman. A team from Rice University has developed single-molecule nanosubmarines that could eventually be used to deliver medicines directly inside the body.
One of science fiction's biggest unfulfilled promises are medical nanobots: tiny little machines that will run around your body and right nature's wrongs. Scientists from the University of Houston are setting out to change all of that, with an incredibly clever self-assembling robotic gun that can clear blockages or inject drugs from inside your body.
There's tiny revolution afoot in medicine, where micro-sized and nano-sized robots will someday cruise around inside our bodies, zeroing in on cancerous cells or repairing damaged but otherwise healthy ones. But before those ideas all become reality, those bots need a power source inside our bodies. That power source could be stomach acid.
Researchers want to use microscopic nanobots for drug delivery and other tasks inside the human body, but there are still places the micro machines can't get. Now, scientists have made the smallest bot yet, a magnet-guided corkscrew so tiny, it can sneak through the pores in human connective tissue.
A team of Dutch engineers just published the details of a curious new invention: tiny robotic sperm that can be controlled with a weak magnetic field. Like real sperm, these so-called MagnetoSperm flip their tails to swim towards their target. Unlike real sperm, they're made of metal-coated polymer.
Yesterday we learnt that scientists have created the first nanobot assembly line. The assembly line is "manned" by four spider-like nanocreatures made from DNA strands, with three arms and four legs. That's what you are looking at in this image.
