Nanotechnology is the science and technology of diagnosing, treating and preventing disease and traumatic injury; of relieving pain; and of preserving and improving human health, through the use of nanoscale-structured materials, biotechnology and genetic engineering, and eventually complex molecular machine systems and nanorobots.
Prospective of a nanotech world:
Ø It helps in the detection of tumor location, size, shape at a molecular level
Ø Delivery of anticancer drugs to specific site
Ø Target specific imaging
Ø Overcome both non cellular and cellular-based drug resistance, to increase selectivity of drugs.
Ø Remove microvascular obstruction
Ø Perform non invasive tissue transplants
Ø Molecular repairs
Ø Exchange new whole chromosomes

Goodbye to dental drills: Nanoneedles and Nanotweezers
Ø Restoration of tooth structure with fluoride,calcium,phosphate releasing nanocomposites.
Ø Dental enamel formation using nanorods, nanospheres, and recombinant amelogenins.
Ø Delivery of Local anesthesia
Ø Dentition renaturalization
Ø Permanent hypersensitivity cure
Ø Complete orthodontic realignments during a single office visit
Ø Continuous oral health maintenance using mechanical dentif-robots incorporated in mouthwash & toothpaste.
