Introduction The term “Nanotechnology” generally refers to engineering
& manufacturing at nanometer length scale.
The possibility of nanorobots was first proposed by Richard Feyman in 1959.
Nanotechnology gives us specially engineered drugs which are nanoscale cancer seeking missiles.
Nanomedicine is the process of diagnosing, treating and preventing disease and traumatic injury of relieving pain and of preserving and improving human health using molecular tools and molecular knowledge of the human body.
Nano-biotechnologyNano-biotechnology is rapidly advancing technology that
applies the tools & processes of microfabrication to build
devices to study biosystem.
The research and development of nanorobots with
embedded nanobiosensors and actuators is considered a
new possibility to provide new medical devices for
doctors.
AppearanceIt is impossible to say exactly what a generic nanorobot
would look like.
Each species of medical nanorobot will be designed to
accomplish a specific task, and many shapes and sizes are
possible.
Each nanorobot will be on the order of perhaps 0.5 micron
up to perhaps 3 microns in diameter.
ControlBecause of the small dimensions of the Nanorobots, on board
computation will be limited. One solution to that problem is to do the computation on a central computer that receives sensor data from the Nanobots and sends them orders.
To help control nanorobot position, a system for tracking an object in space can comprise a transponder device connectable to the object.
The transponder device has one or several transponder antennas through which a transponder circuit receives an RF (radio frequency) signal.
Navigation
External navigation systems might use a variety of different methods to pilot the nanorobot to the right location. One of these methods is to use ultrasonic signals to detect the nanorobot's location and direct it to the right destination.
Using a Magnetic Resonance Imaging (MRI) device, doctors could locate and track a nanorobot by detecting its magnetic field.
Doctors might also track nanorobots by injecting a radioactive dye into the patient's bloodstream.
Powering the Nanorobots A Nanorobot with mounted electrodes could form a battery
using the electrolytes found in blood.
Nanorobots could get power directly from the blood stream.
The Nanorobot would hold a small supply of chemicals that
would become a fuel source when combined with blood.
A nanorobot could use the patient's body heat to create powe.
Locomotion The scientists manipulate the arms by creating magnetic
fields outside the patient's body.
The magnetic fields cause the robot’s arms to vibrate,
pushing it further through the blood vessels.
Another potential way nanorobots could move around is
by using a vibrating membrane. By alternately tightening
and relaxing tension on a membrane, a nanorobot could
generate small amounts of thrust.
Application
It is clear that very "simple" medical Nano devices can have
extremely useful abilities, even when applied in relatively
small doses.
Heart attack coagulation, kills cancer cells, operates the
tumor.
Kidney stones.
Liver stones.
In mechanical field these can be used to study the
microstructure of a metal by mixing nanorobots with
lubricating oil or required solution.
ConclusionNanorobots in medicine will eliminate virtually all
common diseases of the 20th century, virtually all
medical pain and suffering, and allow the extension of
human capabilities most especially our mental
abilities.
