Nanotechnology in dentistry.

Nanotechnology is manipulating matter at nanometer level and the application of the same to medicine is called nanomedicine. Nanotechnology holds promise for advanced diagnostics, targeted drug delivery, and biosensors. In the long-term, medical nanorobots will allow instant pathogen diagnosis and extermination, individual cell surgery in vivo, and improvement of natural physiological function. Current research is focusing on fabrication of nanostructures, nanoactuators, and nanomotors, along with means to assemble them into larger systems, economically and in great numbers.
