Nanomedicine
Some medicines are made throughbiotechnological processes, for example
those using recombinant DNA (human
hepatitis vaccine)
Under these processes the DNA of living
creatures (usually bacteria) is altered
Nanotechnology represents a similar
approach to the manufacture ofpharmaceuticals and other goods.

Nanorobots: Medicine of the
Future
What are they?
Nanorobots are nanodevices that will be
used for the purpose of maintaining and
protecting the human body againstpathogens.
They will have a diameter of about 0.5 to 3
microns and will be constructed out of parts
with dimensions in the range of 1 to 100nanometers

Nanorobots
The powering of the nanorobots can bedone by metabolizing local glucose and
oxygen for energy
Other sources of energy within the bodycan also be used to supply the necessary
energy for the devices
They will have simple onboard computers
capable of performing around 1000 or fewercomputations per second.

Nanorobots
A navigational network may beinstalled in the body, which may
provide high positional accuracy to all
passing nanorobots
This will enable the physician to keep
track of the various devices in thebody
