  1. 1. Nano
  2. 2. NANO TECHNOLOGY• Nanotechnology (sometimes shortened to "nanotech") is the study of manipulating matter on an atomic and molecular scale. Generally, nanotechnology deals with structures sized between 1 to 100 nanometer in at least one dimension, and involves developing materials or devices within that size.
  3. 3. ROBOTICS• Robotics is the branch of technology that deals with the design, construction, operation, structural disposition, manufacture and application of robots. Robotics is related to the sciences of, enginnering, electronics, mechanics and software
  4. 4. What is Nanorobotics?• Programmable assembly of nm-scale components either by manipulation with macro or micro devices, or by directed self-assembly.• Design and fabrication of robots with overall dimensions at or below the mm range and made of nm-scale components.• Programming and coordination of large numbers (swarms) of such nanorobots.
  5. 5. • Known as nanorobot pioneer, adriano Cavalcanti is the medical nanorobotics inventor for the pratical hardware architecture of nanorobots, which was integrated as a model based on nanobioelectronics for applications in environmental monitoring, brain aneurysm, diabetes, cancer and cardiology. His advanced prototype provided a suitable integrated circuit approach, using an effective wireless platform
  6. 6. NANOBOT ISSUES• Sensors• Computers and Control• Actuators and Propulsion• Power• Communications• Interfaces and Integration – nano/micro/macro – organic/inorganic – biotic/abiotic• Programming and CoordinationNanorobots raise all the issues that are important for NEMS
  7. 7. CONSTRUCTION AND DESIGN• Designs derived from biological models• Components: onboard sensors, motors, manipulators , power suppliers,molecular components• Best known biological sample is ribosome used to constuct robotic arm• Manipulator arm driven by detailed sequenc e of controlsignals• Control signals received by robotic arm via on board sensors using broadcast architecture• Assemblers are molecular machine system perform molecular manufacturing on atomic scale

  11. 11. APPLICATIONS IN MEDICAL FIELD• Breaking up blood clots• Fighting cancer• Parasite removal• Gout• Breaking up of kidney stones• Arterioscleriosis
  12. 12. Nanorobots might carry small ultrasonic signalgenerators to deliver frequencies directly to kidney stones
  13. 13. Nanorobots may treat conditions likearteriosclerosis by physically chipping away the plaque along artery walls
  14. 14. Microorganism Detection PEI/PEG algae Nanowire/NanotubeElectrode antibody SiO2 Si Substrate
  15. 15. Nanowire Detection of Algae in a Microchannel Algae cells 150 B add algaeC A 145 140 I (nA)Nano sensor 135 S D 130 SiO2 700 750 800 850 900 950 1000 Time (Sec)
  16. 16. NANO SENSORS• Provides realtime information about antibodies to antigens, cell receptors to their glands etc..• Used for drug detection• To detect chemical vapours at low concentation based on surface stress.
  17. 17. IN SPACE TECHNOLOGY• Nanorobots can be used to actively repair damaged suit materials while an astronaut is in the field• specialized Marssuit Repair Nanorobots (MRN). MRN nanorobots operate as space-fillingpolyhedra to repair damage to a Marssuit• Measurement of toxic elements in environment
  18. 18. NANOBOTS CAN MINE GARBAGE DUMPS• Nanobots are going to make it easier and cheaper to pull out, clean up and create useful commodities for us to reuse. And once you understand the vast potential for Nanotechnology, you are going to understand that our future is going to be so bright... it is going to be so ……….freakin brilliant!
  19. 19. • With 15,342 atoms, this parallel-shaft speed reducer gear is one of the largest nanomechanical devices ever modeled in atomic detail
  20. 20. ADVANTAGES• The microscopic size of nanomachines translates into high operational speed• individual units require only a tiny amount of energy to operate• Durability is another potential asset• nanites might last for centuries before breaking down
  21. 21. DISADVANTAGES• risk of cancer• may affect human health by introducing toxicity in blood• Replication may become out of control
