Nanorobots for Health Care in Human Bodies

Nanotechnology in Nanorobots is going to be available very soon for the future generations, they need not worry about going to doctors or pharmaceutical shop and also no health problems. This technology gives a strong promise to give the powerful medicine. Many proposed solutions in the nano-medicine will have nanorobots, which serves as antibodies in the weak immune system, unblocking arteries affected by plaque, curing diseases, construction of replacement body organs, repairing damaged tissue, unresponsive to conventional methods and more.

A nanorobot is a very small machine designed to perform some special tasks precisely at nano-scale dimensions and repeatedly. These will have a diameter of about 0.5 to 3 microns and constructed with dimensions ranging from 1 to 100 nano-meters. These robots have a strong potential to revolutionize healthcare for treating diseases in future. This opens new paths for further research. It is likely to change human life and healthcare more deeply than other developments have done.

Importance of nanorobots in healthcare

1. Blood clot
Nano robots help in reducing the complications of blood clot from muscle death to stroke by braking it up. The robot here must be able to remove blood clots without losing small pieces in blood stream but this is difficult and is problematic as it travels the entire body and creates issues. In order to encounter the wound and clot the blood in a fraction of a second, the system of clottocyte nanorobots would store fibers and after finding out the wound, the nanorobots would disperse their fibers, will come together to create a clot that platelets do.

2. Nanorobotic dentifrice
For major tooth repairs, nano-dental techniques are used. This involves many tissue engineering procedures. With the help of this latest developments in nanotechnology it is able to stimulate the bio-mineralization process which can create dental enamel and hardest tissues in human body.

3. Microbivore nanorobots
Microbivore nanorobots function in a way similar to the white blood cells do. But they are much faster in destroying the bacteria. This will eliminate the infections caused by the bacteria in minutes in contrast to the antibiotics that takes weeks to cure the infection.

4. Respirocyte nanorobots
Respiratory nanorobots function as red blood cells in the human body. These robots are designed to carry more oxygen than the natural cells do. This is very helpful for the patients who are suffering from anemia. These robots will have a tank carrying oxygen at high pressure, sensors for determining concentration of oxygen in bloodstream and a valve for releasing oxygen when sensors determine for the additional oxygen.

5. Surgical nanorobots
These robots are used in surgical operations. These are introduced in to the body with the help of vascular system or at the ends of catheters into various vessels and also in to the other cavities in the human body. This device performs various functions like searching for pathology and correcting and diagnosing injuries with nano-manipulation coordinated by an on-board computer by maintaining contact with the supervising surgeon through ultra sound signals that are coded.

6. Nanorobots break kidney stone
Large kidney stones can be easily broken by using ultrasonic frequencies but this is not much effective so, nanorobots break stones using small laser.

7. Nanorobots fight against cancer
These robots fight cancer. Cancer is successfully treated with current medical therapy tools and technologies. The important point to be noted is early diagnosis and and successful drug delivery for decreasing the side effects of chemotherapy. Nanorobots with chemical bio-sensors are used for detection of tumor cells in early stages and to find intensity of signals integrated nano-sensors are used.

8. Cellular repair nanorobots
These robots can prevent damage caused by comparatively clumsy scalpels by working at cellular level.

Apart from the wonders that nanorobots create, there are disadvantages: clustering of nanorobots causes harm; installation and maintenance cost is high as well.

Nanorobots has wonderful application from eradicating disease to reversing aging and nanomedicine allows for personalized treatment for many diseases and helps in in-depth understanding of diseases at molecular levels.
