  • 2. Contents What is a robot? What is a nanobot? ‘Nano scale’ concept illustration Types of nanobots Different approaches for building nanomaterials Hardware components in a nanobot Applications in medical field Advantages and disadvantages Conclusion References
  • 3. What is a robot? A robot is a mechanical or virtual artificial agent, usually an electro- mechanical machine that is guided by a computer program or electronic circuitry. Robots can be autonomous or semi- autonomous.
  • 4. What is a Nanobot? Nano-Robots are the robots that are simply known as the controllable machines at the nano meter or the molecular scale, composed of nano-components.
  • 5. What do you mean by the term ‘nano-scale’? The word ‘Nano’ means a scale of 10−9 metre; having or involving dimensions of less than 2000 nanometres. Most common examples of nano-scale substances are Fullerene, our DNA, Carbon Nano Tubes..etc For a size comparison, the width of the human hair is said to be greater than 50,000 nanometers.
  • 6. Types of nanobots Biochip Nubots Bacteria based Virus based
  • 7. Biochip based nanorobot Usually built by the joint use of nanoelectronic components such as single electron transistors, carbon nano tubes, one dimensional nano wires etc and some bio-material components to interact with biological systems.
  • 8. The top down approach Top down lithography Electronic devices Chip masks Computer chips NEMS Cutting, etching, grinding Precision engineered surfaces High quality optical mirrors
  • 9. The bottom up approach Bottom up Self assembly Crystal films and tubes Displays, programmable nano processors Positional assembly Experimental atomic or molecular devices
  • 10. Schematic illustration of top down and bottom up approaches
  • 11. Hardware components in a nanobot Biosensor Actuator Power supply Data transmission Logic processor/ nano processor
  • 12. Biosensor A biosensor is an analytical device, used for the detection of an analyte, that combines a biological component with a physicochemical detector. The sensitive element may be biological or bio mimetic component that interacts the analyte under study. The transducer or the detector element converts these signals into a form which can be easily processed and quantified by the logic unit.
  • 13. Flexure-FET biosensor
  • 14. actuator Different kinds of actuators such as electromagnetic, piezoelectric, electrostatic and electro thermal etc.. ATP, DNA and RNA can be used as a biological alternative for nanomotors. Fullerence with CNT as conductive structures permits electrostatically driven motors providing the force necessary for micromanipulation
  • 15. Power supply Power source Internal Blood flow Body heat Electrolytic fluids External Inductive coupling Radio waves
  • 16. Principle of inductive coupling
  • 17. Data transmission Acoustic, chemical, light and Radio frequency are possible choices Chemical signal useful for short range communication Acoustic signals are more suited for long range communication Resolutions of 700nm can be achieved by using acoustic signalling Transmission through RF @ 4.5 KHz frequency Transmission through sonar:-20uW@8Hz for 3V supply
  • 18. Logic processor/Nanoprocessor First programmable logic processor manufactured my MITRE corp in association with Harvard university in 2011 ‘Bottom up’ method of fabrication. Multiple arithmetic and logical functions can be implemented on the “Tile” Each ‘tile’ consist of precisely engineered and fabricated Si-Ge nanowires surrounded by insulating metal oxides Operating speed achieved:-100 MHz, speeds achievable in future:- 2THz Transistor length:-20nm, 10nm for CNT

  • 22. How nanobots can help
  • 23. ABF OR ARTIFICIAL BACTERIA FLAGELLA Developed by university of Zurich, Switzerland Total length is around 20 micrometers Fabricated by vapor depositing ultra thin layers of gallium, indium, arsenic and chromium on substrate and are then patterned from it through lithography This form super thin narrow ribbons that curl themselves into a spiral shape when detached from substrate Thickness and composition of the deposited layer defines the size and shape of the spiral Propulsion via magnetic field, applied to the Cr-Ni-Au ‘head’ of the robot.
  • 24. FABRICATION STEPS AND STRUCTURE
  • 25. ABF IN ACTION
  • 26. GOOGLE NANOBOTS Project officially launched in the year 2014 multiple sets of nanoparticles capable of identifying specific diseases and anomalies stored in a MEP. And delivered through IV. These nanoparticles, once released into the blood, binds to the tumour Can send real time report to the user, GUI in a wristband Data transmitted to the physician wirelessly through RF.
  • 27. GOOGLE NANOBOT CONCEPT
  • 28. By using nanobots, we can pinpoint the location of the anomaly Capillaries with a diameter of 20 micrometers are accessible Hypoxia treated by introducing respirocytes. Gene manipulation in germ cells and rectification of chromosomal disorders Brain mapping and transhumanization. Advantages of nanorobots
  • 29. Disadvantage of nanorobots Hardware and control techniques are still in its infancy and are not ready for commercial prime time applications Technology can be reverse engineered by hostile organizations to the molecular level and wreck havok on the unsuspecting public.
  • 30. Conclusion Nanorobots are highly useful in the field of medicine Advancements in STM, SEM help to build nano-scale designs CNT based FET’s can pave way for a whole new levels of nanocomputing in the future and thus pave way for a Fully autonomous Nanobot Life span extended, Diseases cured.
