INTRODUCTION

Nanorobots might function at the atomic or molecular level to build devices, machines, or circuits, a process known as molecular manufacturing.

. .

Nanorobots might also produce copies of themselves to replace worn-out units, a process called self-replication.

It has been suggested that a fleet of nanorobots might serve as antibodies or antiviral agents in patients with compromised immune systems, or in diseases that do not respond to more conventional measures. There are numerous other potential medical applications.

A major advantage of nanorobots is thought to be their durability.

APPLICATIONS OF NANOROBOT

Gout

Cleaning wound

Breaking of kidney stone

Fighting cancer

Treating arteriosclerosis

Breaking of clots

Parasite removal

Breaking up blood clots: Nanorobots could travel to a clot and break it up. This application is one of the most dangerous uses for nanorobots – the robot must be able to remove the blockage without losing small pieces in the bloodstream, which could then travel elsewhere in the body and cause more problems. The robot must also be small enough so that it doesn't block the flow of blood itself.

•Breaking up kidney stones: Kidney stones can be intensely painful -- the larger the stone the more difficult it is to pass. Doctors break up large kidney stones using ultrasonic frequencies, but it's not always effective. A nanorobot could break up a kidney stones using a small laser.

Nanorobots might carry small ultrasonic signal generators to deliver frequencies directly to kidney stones.

•.

•Parasite Removal: Nanorobots could wage micro-war on bacteria and small parasitic organisms inside a patient. It might take several nanorobots working together to destroy all the parasites.

•Gout: Gout is a condition where the kidneys lose the ability to remove waste from the breakdown of fats from the bloodstream. This waste sometimes crystallizes at points near joints like the knees and ankles. People who suffer from gout experience intense pain at these joints. A nanorobot could break up the crystalline structures at the joints, providing relief from the symptoms, though it wouldn't be able to reverse the condition permanently.

•Cleaning wounds: Nanorobots could help remove debris from wounds, decreasing the likelihood of infection. They would be particularly useful in cases of puncture wounds, where it might be difficult to treat using more conventional methods.

Nanorobot NavigationThere are three main considerations scientists need to focus on when looking at nanorobots moving through the body -- navigation, power and how the nanorobot will move through blood vessels.. These can be divided into one of two categories: external systems and onboard systems.External navigation systems : One of these methods is to use ultrasonic signals to detect the nanorobot's location and direct it to the right destination. The signals would either pass through the body, reflect back to the source of the signals, or both. The nanorobot could emit pulses of ultrasonic signals, which could be detected using special equipment with ultrasonic sensors. 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. Other methods of detecting the nanorobot include using X-rays, radio waves, microwaves or heatOnboard systems, or internal sensors, might also play a large role in navigation. A nanorobot with chemical sensors could detect and follow the trail of specific chemicals to reach the right location. A spectroscopic sensor would allow the nanorobot to take samples of surrounding tissue, analyze them and follow a path of the right combination of chemicals.  

Powering the NanorobotJust like the navigation systems, nanotechnologists are considering both external and internal power sources. Nanorobots could get power directly from the bloodstream. A nanorobot could use the patient's body heat to create power, but there would need to be a gradient of temperatures to manage it. Power generation would be a result of the Seebeck effect.capacitor which has a slightly better power-to-weight ratio can also used.Another possibility for nanorobot power is to use a nuclear power source.

External power sources include systems where the nanorobot is either tethered to the outside world or is controlled without a physical tether. Tethered systems would need a wire between the nanorobot and the power source. The wire would need to be strong, but it would also need to move effortlessly through the human body without causing damage. A physical tether could supply power either by electricity or optically. experimenting with in Montreal, can either manipulate the nanorobot directly or induce an electrical current in a closed conducting loop in the robot.

Nanorobot particals will penetrate living cells and accumulate in animal organs and can perhaps enter the food chain.

There is no regulatory body dedicated to check this potents & powerful invasion.

Changing in the proteins due to presence of nanoparticals in the blood stream could trigger dangerous effects like blood clotting.

Reactance of humans and existing environment to these nanoparticals and their acceptance is not known.

Nanorobots: Today and TomorrowTeams around the world are working on creating the first practical medical nanorobot. robot ranging from a millimeter in diameter to a relatively hefty two centimeters long already exist, though they are all still in the testing phase of development and haven't been used on people. We're probably several years away from seeing nanorobots enter the medical market. Today's microrobots are just prototypes that lack the ability to perform medical tasks.In the future, nanorobots could revolutionize medicine. Doctors could treat everything from heart disease to cancer using tiny robots the size of bacteria, a scale much smaller than today's robots. Robots might work alone or in teams to eradicate disease and treat other conditions.. Unlike acute treatment, these robots would stay in the patient's body forever. Another potential future application of nanorobot technology is to re-engineer our bodies to become resistant to disease, increase our strength or even improve our intelligence. Will we one day have thousands of microscopic robots rushing around in our veins, making corrections and healing our cuts, bruises and illnesses? With nanotechnology, it seems like anything is possible

A nanostructured data storage device about the size of a human live cell is implanted in the brain could store a large amount of data and provides extremely rapid access to this information.

But perhaps the most long-term benefit to human society as a whole could be the drawing of a new era of peace.We could hope that the people who are independently well fed ,well housed,smart,well educated,healthy & happy will have little motivation to make war.Human being who have reasonable prospect of living “normal” lifetime will learn patience from experience,and will be extremely unlikely to risk those “many lifetimes” for any but most of compelling reasons.

“A scientific truth does not triumph by convincing its opponents and making them see the light, but rather because its opponents eventually die and a new generation grows up that is familiar with it.”
