Here comes a quiet revolution in the world of implantable/injectable medical devices. According to a publication in Nature Materials, two scientists from the UChicago labs are on they way to design a device that would be not just small, but tiny, even in comparison to the width of a human’s hair. This light-activated injectable device would be able to stimulate nerve cells and eventually control organs behavior.

Only one particle of the device would need to be injected in order for it to work. Another bright side – no need for a removing surgery as the device would degrade in a couple of months.
