What Does Nanotechnology Mean?
Nanotechnology is the engineering of functionalsystems at the molecular scale.
It is the study of manipulating matter on
an atomicandmolecularscale.

NANOROBOTS
A nanorobot is a tiny machine designed to perform a
specific task or tasks repeatedly and with precision at
nanoscale dimensions, that is, dimensions of a
few nanometers (nm) or less, where 1 nm = 10-9 meter
They are nanodevices that will be used for the purpose ofmaintaining and protecting the human body against
pathogens.

MolecularNanotechnology (MNT)
The umbrella science ofnanomedicine
MNT describes
engineered nanosystems
(nanoscale machines)
operating on the molecular
scale.
MNT is especiallyassociated withthe molecular assembler, a
machine that can produce a
desired structure.
MNT IS based on theability to build structures to
complex, atomic
specifications by meansofmechanosynthesis.

` Molecular nanotechnology (MNT) is a
breakthrough science that combines principles of
chemistry, biology and physics to propose
microscopic devices on the nano-scale that wouldmechano chemically manipulate individual atoms
and molecules for the purpose of constructing
materials, eradicating disease, and restoring the
environment; thus making the potential benefits
of MNT wide-ranging and revolutionary.

` The powering of the nanorobots can be done by
metabolizing local glucose and oxygen for energy. In a
clinical environment, another option would be externally
supplied acoustic energy.
` Other sources of energy within the body can also be usedto supply the necessary energy for the devices.
` They will have simple onboard computers capable of
performing around 1000 or fewer computations per second.
This is because their computing needs are simple.` Communication with the device can be achieved
by broadcast-type acoustic signaling

Devices working in thebloodstream could nibble
away at arteriosclerotic
deposits, widening the
affected blood vessels.
Cell herding devicescould restore artery walls
and artery linings to
health, by ensuring that
the right cells and
supporting structures arein the right places.
This would prevent
most heart attacks.

FIBRE OPTICS TECHNOLOGY: Utilized in endoscopic
medicine.Fiber optic instruments are introduced into the body
cavity through a tiny hole made on the body to either to
investigate or treat and ailments.
LASER TECHNOLOGY: Laser technology is utilized in
cataract surgery and removal gall bladder stones.
TELEMEDICINE: With these facility doctors in remote areas
can benefit from the expertise of the specialist urban centers.
SOUND WAVES: Utilized in investigative and therapeuticultrasonography.
NUCLEAR RADIATION: Utilized in the treatment of cancer
and in investigations like x-ray.

All of these current developments in technology directs humans a step
closer to nanorobots and simple, operating nanorobots is the near
future. Nanorobots can theoretically destroy all common diseases of
the 2lst century thereby ending much of the pain and suffering. It can
also have an alternative, practical uses such as improved mouthwash
and cosmetic creams that can expand the commercial market inbiomedical engineering. People can envision a future where people
can self-diagnose their own ailments with the help of nanorobot
monitors in their bloodstream. Simple everyday illnesses can be cured
without ever visiting the physician.
