Dentists may soon be getting a potent new weapons with which to wage the global fight against cavities. The University of Maryland has developed a novel new nanocomposite material that can be used not only as filling for cavities, but that will also kill any remaining bacteria in the tooth and regenerate the actual structure lost to decay.
Wiretapping an enzyme and listening as it unfolds could shed new light on the way proteins work, allowing researchers to monitor structural changes over a longer period of time than was previously possible. To do it, scientists tethered a nanoscale transistor to a molecule found in human tears.
Nanotechnology promises to enable tiny, intricate circuits powering devices on any surface. But unless they're harvesting energy from something like a heartbeat, the devices can only be as small as the smallest battery.
Now researchers at Rice University have combined the two, packing an entire lithium-ion battery into a single nanowire. The developers say it's as small as such a device can possibly get.
