Nanotechnol Nanometre Nano- stuff Nanomedicine Nanoscience Nanobots A prefix that means very, very, small. The word nano is from the Greek word ‘Nanos’ meaning Dwarf. It is a prefix used to describe "one billionth" of something, or Nano:

Nanotechnol Nanometre Nano- stuff Nano-Produ Nanomedicine Nanoscience Nanobots A part of science that studies small stuff. It’s not biology, physics or chemistry. It’s all sciences that work with the very small. Nanoscience

Nanotechnol Nanometre Nano- stuff Nano-Produ Nanomedicine Nanoscience Nanobots Nanotechnology Includes advances in all industries, including the electronic, chemical, and pharmaceutical. The art and science of making useful stuff that does stuff on the nanometre length scale.

Nanorobotics is the technology of creating machine or robots at or close to the scale of nanometre(10 -9 ) NANOROBOTS Nanorobots(Nanobots,Nanoids,Nanites or Nanomites)would typically be devices ranging in size from 0.1 to 10 micrometer and constructed of nanoscale or molecular components.

Nanorobots are nanomachines embedded in our body performing their duties as disciplined soldiers. Before being sent into the body on their search on destroy mission, they have to be programmed with a set of characteristics that let them clearly distinguish their targets from everything else.

ADVANTAGES

It is the medical application of nanotechnology. It`s defined as the repair, construction and control of human biological systems using devices built upon nanotechnology standards.

INJECTION OF NANOROBOTS Find a way to introduce nanorobots into the body for surgery.Allow it to do the operation without ancillary damage.So the nanorobots are made smaller than the blood vessels as it can travel.Femoral artery in the leg is considered to be a largest artery in our body.So the nanorobot is injected in this artery.

NAVIGATION OF NANOROBOTS 1)BLOOD STREAM  Every living thing needs area to move.  Nanorobots use blood flow for its movement.  In order to move the nanorobots in blood flow, Speed of blood Get through the heart without stuck React with changes in blood flow rate  Able to change the direction according to the blood stream  To satisfy this, nanorobots should be made with electric motor to turn propeller.

To know the location of nanorobots where it goes we use 1)Ultrasonic technique  ultrasonic signals beamed into body, and either reflected back or received on other side of the body.  The received signal is processed to obtain information about the material through which it has passed.

DESTRUCTION The fatty deposits (or) clots are removed using special blades fitted with nanorobots.Continuous (or) pulse signal is used to activate the blades.

To cure skin diseases, a cream containing nanorobots may be used. It could remove the right amount of dead skin, remove excess oils, add missing oils, apply the right amounts of natural moisturising compounds, and even achieve the elusive goal of 'deep pore cleaning' by actually reaching down into pores and cleaning them out. The cream could be a smart material with smooth- on, peel-off convenience.

It is also used in the treatment of kidney stone.

It is used to inject sperms.

It is used to repair damaged cells.

REMOVAL OF NANOROBOTS To take nanorobots from the body we use two methods one is retrace our path upstream another is making small surgery to remove.

CONCLUSION  The nanorobots are used in heart surgery, due to this number of risks and side effects behind is reduced.  The same technique is used in various treatments like cancer, breaking kidney stones, breaking liver stones, parasite removal only with slight modification.  Within ten years several advancement technologies should be made from this nanorobotics.
