This document discusses the potential applications of nanotechnology in the field of medicine and healthcare. It describes how nanotechnology operates at the molecular level and can be used to transport drugs directly to specific cells. The document outlines several areas where nanotechnology may transform medicine, including nano-diagnostics, regenerative medicine, nanorobotic microbivores to destroy pathogens, and surgical nanorobotics to perform minimally invasive surgery guided by a human surgeon. The document speculates that within 10-20 years, nanotechnology could enable complete dentition replacement during a routine dental visit and repair of teeth at the molecular level using nanorobots. In conclusion, the document argues that nanotechnology holds great promise but also risk, and will profoundly

NANOTECHNOLOGY
 Nanotechnology is the engineering of
functional systems at the molecular
level. The field combines elements of
physics and molecular chemistry with
engineering to take advantage of
unique properties that occur at
nanoscale.
 One practical example of this
technology is the use of tiny carbon
nanotubes to transport drugs to
specific cells. Not only do these
nanotubes have low toxicity and a
stable structure, they’re an ideal
container for transporting drugs
directly to the desired cells.

3. TheFutureof
Nanotechnologyin
Medicine
 Around the world, researchers are
increasingly thinking smaller to solve some
of the biggest problems in medicine.
 Though most biological processes happen at
the nano level, it wasn’t until recently that
new technological advancements helped in
opening up the possibility of nanomedicine
to healthcare researchers and professionals.

4. Nanomedicine
 The field of “Nanomedicine” is the science and technology
of diagnosing, treating, and preventing disease and
traumatic injury, of relieving pain, and of preserving and
improving human health, using nanoscale structured
materials, biotechnology, and genetic engineering, and
eventually complex machine systems and nono-robots. It
was perceived as embracing five main subdisciplines that
in many ways are overlapping by common technical issues

6. Nano diagnostics
It is the use of nanodevices for the early disease identification or
predisposition at cellular and molecular level. In in-vitro diagnostics,
nanomedicine could increase the efficiency and reliability of the
diagnostics using human fluids or tissues samples by using selective
nanodevices, to make multiple analyses at subcellular scale
Regenerative medicine
It is an emerging multidisciplinary field to look for the reparation,
improvement, and maintenance of cells, tissues, and organs by
applying cell therapy and tissue engineering methods. With the help
of nanotechnology it is possible to interact with cell components, to
manipulate the cell proliferation and differentiation, and the
production and organization of extracellular matrices

7. Applicationsin
medicine
 Within 10–20 years it should become possible to construct
machines on the micrometer scale made up of parts on the
nanometer scale. Subassemblies of such devices may include
such as useful robotic components as 100 nm manipulate
arms, 10 nm sorting rotors for molecule by molecule reagent
purification, and smooth super hard surfaces made of
automatically flawless diamond.
 Nano computers would assume the important task of
activating, controlling, and deactivating such
nanomechanical devices. Nano computers would store and
execute mission plans, receive and process external signals
and stimuli, communicate with other nano computers or
external control and monitoring devices, and possess
contextual knowledge to ensure safe functioning of the
nanomechanical devices. Such technology has enormous
medical and dental implications.

8. Nanoroboticmicrobivores
 Artificial phagocytes called microbivores could patrol the
bloodstream, seeking out and digesting unwanted pathogens
including bacteria, viruses, or fungi. Microbivores would
achieve complete clearance of even the most severe
septicemic infections in hours or less. The nanorobots do not
increase the risk of sepsis or septic shock because the
pathogens are completely digested into harmless sugars,
amino acids, and the like, which are the only effluents from
the nanorobot.

9. Surgicalnanorobotics
 A surgical nanorobot, programmed or guided by a human
surgeon, could act as a semiautonomous on site surgeon
inside the human body, when introduced into the body
through vascular system or cavities. Such a device could
perform various functions such as searching for pathology
and then diagnosing and correcting lesions by
nanomanipulation, coordinated by an onboard computer
while maintaining contact with the supervising surgeon
via coded ultrasound signals

10. Toothrepair
 Nanorobotic manufacture and installation of a
biologically autologous whole replacement tooth that
includes both mineral and cellular components, that is,
‘complete dentition replacement therapy’ should become
feasible within the time and economic constraints of a
typical office visit through the use of an affordable
desktop manufacturing facility, which would fabricate
the new tooth in the dentist's office.
And many more applications...

11. CONCLUSION
 The visions described in this article may sound
unlikely, implausible, or even heretic. Yet, the
theoretical and applied research to turn them into
reality is progressing rapidly. Nanotechnology will
change dentistry, healthcare, and human life more
profoundly than many developments of the past. As
with all technologies, nanotechnology carries a
significant potential for misuse and abuse on a scale
and scope never seen before. However, they also
have potential to bring about significant benefits,
such as improved health, better use of natural
resources, and reduced environmental pollution.
These truly are the days of miracle and wonder.
