Abstract— this paper reviews the study of the different aspects of nanotechnology in curing the different types of diseases. Nanotechnology is concerned with molecular scale properties and applications of biological nano structures and as such it sites the interface between chemical, biological, and physical sciences.

By definition, Nano technology deals with activities at level of atoms and molecules. A nano meter is a billionth of a meter that is about1 in 80,000parts of the diameter of a human hair, or 10 times the diameter of an H2atom. It is that field of science and technology where dimensions in the range of 0.1 nm to 10 nm play a critical role. Medical technologies expected to utilize nanobots injected into the patient to perform their treatment at a cellular level. The typical medical nano devices will probably be a
II. HOW NANOBOTS ARE MADE:
The ultimate goal and essential definition of nanobot is to have the microscopic entity made entirely out of electromechanical components.Humans are able to perform one
construction behaves one way in relatively large quantities and a completely different way on the nano scale. Microscopic silicon components called transducers have so far been used.
Mainly nanobots are used into human blood vessels to perform functions such as clearing
Traditionally, most robots have a solar cell or some kind of battery pack, but obviously these are too large for nanobot. However, the answer may lie in nuclear technology. Due to nanobots equipped with thin film of radioactive material, nanobots will be able to fuel themselves on particles released by decaying atoms.
Silicon is strong enough to last and conduct electricity. Nanobots can be easily injected into the body due to their
III. REPAIRING OF DAMAGED TISSUES BY NANOBOTS:
Nanobots can repair damaged tissue without pain and trauma. Nanobots are so small that they actually interact on the same level as bacteria and viruses do in our body.
In the USA, the national Nano technology Initiative has claimed that nano technology has potential in treatment of cancer. However, seen no evidence to support the notion that
nanotechnologies will eliminate cancer in the short- to medium term, and feel that such a claim demonstrates an
the bypass surgery, we are going for nanobot, which can replace this techniques efficiently and effectively. These nanobots will remove the clot without any surgical procedure. Just a small incision is made into the femoral artery to insert these nanobot, from where it is moved to the site of the plaque by the use of its nano components that are attached to it.
V. TREATMENT OF PLAGUE:
As soon as the nanobot detects the site of plague using camera and thermometer, it will activate the rotating needle and the
IV. NANO TECHNOLOGY IN HEART BYPASS SURGERY:
The heart bypass surgery reroutes the blood supply around clogged arteries to improve blood flow and oxygen to the heart. The arteries that bring blood to the heart muscle (coron
•Loss of appetite, constipation.
•Swelling in the area from which the segment of blood vessel was removed
•Fatigue, mood swings, feelings of depression, difficulty sleeping
•Muscle pain or tightness in the shoulders and upper back. The incision in the chest or the graft site (if the graft was from
the leg or arm) can be itchy, sore, numb, or bruised.
The surgery may also lead to loss of memory and mental clarity. To overcome all these problems that are involved in
VI. IN CASE OF EMERGENCY:
In case of some unanticipated situations where we want to switch off the nanobot immediately, it can be done by a magnetic switch that has been provided in it. Once the nanobot has been inserted into the body, it starts operational only when a bar magnet is moved over it. This movement of magnet in one direction only makes the magnetic switch in on condition, and the nanobot become active. So if anyhow in between the task of removing the plague, we encounter any problem where shutting off the nanobot is the only solution so we go for making the magnetic switch off by moving the bar magnet again that will terminate all the running functions of this nano machine.
By consensus, nanobots will find their first applications in medical science.
These will be able to repair damaged or diseased tissues in molecular level.
Using an MRI to precisely place the nanobots in the cancerous region, the light causes the devices to heat to 131 degrees Fahrenheit which destroys the cancerous cells but not damaging surrounding tissues.
Nanobots can also be used to cure the wounded parts to heal using nanobots.
They could also perform delicate surgical functions such as closing a split vein.

Nano technology is truly a vast field of research and study, bound only by the limits of human imagination.
Let us hope that this nano technology will lead the upcoming future.
