When we cut ourselves the platelets in our blood rush by the thousands to the location of the cut and start aggregating causing the wound to close. This process is very efficient and operates automatically. Inspired by this extraordinary, yet ordinary, feed of our bodies researchers built autonomous nanobots able to locate and repair cuts in circuits, just like our platelets do in our veins.
Biomaterials researchers at MIT came up with a very tiny device able to monitor vital signs from deep inside the body. It seems a NANO Supermarket speculative product, actually it is a new type of sensor, designed to be ingested by the patient. This invention will make it possible in the near future to monitor the heart rate and breathing from within the gastrointestinal tract.
We have a wide range of yogurts available in the supermarket: flavored, light, biologic, probiotic, drinkable, the choice is vast. But the yogurt developed by MIT researcher Sangeeta Bhatia has something more. For years she has been studying and researching to simplify the diagnosis of cancer. The result is an extraordinary yogurt that could soon implement accurate, young disease diagnosis.
Researchers at UC San Diego announced that they have developed 3D printed microrobots in the shape of fish able to detect and remove toxin from liquid. Smaller than a human hair – only 120 microns long and 30 microns thick – these little creatures multiply quickly: scientists can 3D print hundreds of these fish in seconds.
When acquiring tissue samples for medical diagnosis, doctors have been confined to bulky and invasive instruments. Unlike the scientists in the 1966 sci-film film Fantastic Voyage, we haven’t been able to shrink a submarine and its human crew in order to let them perform some delicate surgery inside the patient body.
But with recent successful experiments, we may see doctors switching from the single forceps to hordes of so-called microgrippers.
As proved by Imogen Heap’s music gloves that turn gestures into music, gloves are a very convenient choice clothing for wearable technology. If you are interested in this technology, Francesca Barchiesi‘s concept, Hand-Tech, might pique your curiosity. Armed with nano-sized devices woven in its fabric, this glove allows the user to translate hand gestures into images, audio or other forms of information.
Medical practices of the future could become much more efficient with the help of nanotechnology. During a recent experiment, an international team of scientists used nano-sized needles in order to promote production of new blood cells. If successful, this technology could be applied to the human body to repair damaged organs and nerves.
