• With nanotechnology, tools and equipment for surgery and diagnostic would be
a lot cheaper yet remain to be effective and state of the art. Medical research and
processes require highly advanced equipment that could be very expensive but
once the equipment is fully developed, its manufacturing would be a lot easier
and faster with the use of nanotechnology. The creation of complex tools that
can diagnose serious diseases with a single laboratory test would minimize
diagnostic costs and treatment. Using tiny nano-built sensors inserted into the
human body for direct contact with the source of ailment would definitely make
medical treatments easier and cheaper.
• With medical nanotechnology, treatment would be more efficient and precise.
Instead of opening the whole body area for surgical purposes, a microscopic
nanotool would spare the patient from bloody and risky surgical processes. With
nanotechnology in the medical field, treatment would be precise, eliminating
trial-and-error drug prescription. With a single laboratory test and highly
technical computers, a detailed image of the body's system and processes can be
automatically spotted including the cause of the disease and its possible treat-
ment. With nanotechnology in the fields of medicine, medical malpractice
would be eliminated and the side effects of taking medicines out of sheer
guessing from the physicians would be avoided.
• With highly advanced medical equipment, potential diseases can easily be
detected and prevented.
• Since diseases can be prevented, the quality of life for mankind would be
improved and lifespan would be increased.
• With the application of nanotechnology in medicine, replacement of body
organs using machines smaller than body cells can be possible. Because of
advanced nanotechnology, candidates for organ replacement and augmentation
will receive far better body organs enhanced by tiny machines introduced to the
body for better organ performance and functions.
• Medical nanotechnology can largely contribute to genetic therapy and
improvement. Diseases can be easily treated if approached at the genetic level.
So instead of treating diseases based on the symptoms, nanotechnology will help
medical practitioners treat the problem by looking at the root cause.
Nanotechnology and Nanomedicine in the Future
Medical diagnosis, proper and efficient delivery of pharmaceuticals, and devel-
opment of artificial cells are the medical fields where nanosized materials have
found practical implementations. As suggested by Freitas, the application of
nanotechnology to medicine, nanomedicine, subsumes three mutually overlapping
and progressively more powerful molecular technologies. First, nanoscale-
structured materials and devices that can be fabricated today hold great promise
for advanced diagnostics and biosensors, targeted drug delivery and smart drugs,
