“NANOROBOTS”

1. “NANOROBOTS” NANOBOT Under the guidance of, Mr. Subramanya M.B Lecturer, dept. of ML B.G.S.I.T By, Rashna Shadeem (4BW06ML016) nanorobots

2. CONTENTS • Introduction. • Nanorobots in heart surgery. • Structure of nanorobots. • Injection of nanorobot. • Navigation. • Positioning. • Detection. • Destruction. • Applications. • Advantages. • Conclusion. • Reference. nanorobots

3. Introduction WHAT ARE NANOROBOTS? • Nanorobots are tiny machines used to cure diseases in human or in any organism. • Performs task at nanoscale dimensions. • The size of nanorobots is 10 -9. • The prefix ‘nano’ means billionth. nanorobots

4. USE OF NANOROBOTS IN HUMAN BODY • A doctor offers the patient an injection of a nanorobot. • Seeks out cancer cells and destroy them. • Dispells the disease at the source, leaving the healthy cells • untouched. • The patients has no awareness of devices working inside • them. nanorobots

5. NANOROBOTS IN HEART SURGERY • Blood vessels play an important role in supplying blood • to all parts of our body. • Due to the fatty deposition on the walls of blood vessels • blood will not move freely to all parts. • These leads to heart attacks and damage the vital • organs. nanorobots

6. STRUCTURE OF NANOROBOTS Consists of, • Molecular sorting rotors • Propeller • Fins • Sensors Fig: Structure of nanorobots. (http://www.nanorobotdesign.com/article/NNNetwork/indexphp.htm) nanorobots

7. Continued…… • Molecular sorting rotors: • Made up of carbon nanotubes. • Sheet of carbon atom forms a • carbon nanotubes. • SWNT’s can be used to generate mechanical motion. • Nanotube with nanogears used for changing the direction of movement. Fig: Structure of nanorobot nanorobots

8. Continued….. • Propeller: • Like that in nanorobots it is used to drive forward against • the blood stream. • Fins: • Fitted along with the propellers used to propel the device. • Sensors: • Fitted externally and internally with the nanorobots to receive the • signal for correct guidance. Fig: Structure of nanorobot nanorobots

9. 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. nanorobots

10. NAVIGATION • Every living thing needs area to move. • Nanorobots use blood flow for its movement. • In order to move the nanorobots in blood flow, • To satisfy this, nanorobots should be made with electric motors to turn propeller. Fig: Navigation of nanorobots into blood vessels. (http://www.scribd.com/search?cat=redesign&q =nanorobot+in+heart+sugery&sa.x=31&sa.y=18) • 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 nanorobots

11. POSITIONING • To know the location of nanorobots • where it goes we use • ultrasonic technique. • Nanorobots must be able to produce • ultrasonic waves by passing a signal to • piezoelectric membrane. • Several signal processing techniques • are used to track this ultrasonic signal • and to find the location at any time.

12. DETECTION Fig: Nanorobots towards a destination [ref(6)]. • Sensors are used to locate the fatty deposits. • To control the nanorobots as per our wish fit the TV camera . • Sensors are used to receive the signals and do the operations • according to signals send by remote control unit. nanorobots

13. DESTRUCTION • The fatty deposits (or) clots are removed using special blades fitted with nanorobots. • Continuous (or) pulse signal is used to activate the blades. Fig: View of nanorobot removing the fatty deposit [ref(4)]. • To take nanorobots from the body we use two methods one is retrace our path • upstream another is making small surgery to remove. nanorobots

14. APPLICATIONS • Treating arteriosclerosis • Breaking up blood clots • Fighting cancer • Parasite Removal • Breaking up kidney stones nanorobots

15. ADVANTAGES OF NANOROBOTS • Rapid elimination of disease. • Nanorobot might function at the atomic and molecular level to build devices, • machines or circuits known as molecular manufacturing. • Nanorobots might also produce copies of themselves to replace worn-out • units, a process called self-replication. • The major advantage of nanorobots is thought to be their durability, in • theory, they can remain operational for years, decades or centuries. nanorobots

16. 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 year several advancement technologies should be made from this nanorobotics. nanorobots
