Introduction to Nanotechnology K.A. Dimuthu Dharshana Introduction to Nanotechnology K.A. Dimuthu Dharshana Presentation Transcript

  • K.A. Dimuthu Dharshana, Department of Mechanical & Manufacturing Engineering, Faculty of Engineering, University of Ruhuna. Galle, Sri LankaCCPDHE, Faculty of Medicine,University of Ruhuna - 16th May 2012 1
  • 2 Genetics Artificial Intelligence/ Robotics Information Technology Nanotechnology
  • 3 CONTENT  What is Nanotechnology  Few Applications of Nanotechnology
  • 4 N ANOTECHNOLOGY IS A ..  field of Applied Science whose theme is the control of matter, its properties on an atomic and molecular scale. • Physical • Chemical • Electrical • Mechanical • Optical • Magnetic • •
  • 5 H OW SMALL NANOMATERIAL ? Nano fibers Single Human Hair
  • 6 N ANO SCALE …
  • 9 F UTURE TREATMENTS  Nanodevices can make gene sequencing more efficient. It will revolutionize the specificity of diagnostics and therapeutics,  No operations, No more pills and chemotherapies,  Just one quick injection,  The nano sized machine communicate and target millions of different foreign bodies/ matters that may have developed in the body,  It will search and destroy foreign objects, and rebuild the bodies vital cells.
  • 10 Nanotechnology has been a boon for the medical field by delivering drugs to specific cells using nanoparticles. The overall drug consumption and side-effects can be lowered significantly by depositing the active agent in the morbid region only and in no higher dose than needed. This highly selective approach reduces costs and human suffering.
  • 11 F UTURE CANCER TREATMENTS  Nano molecules will travel and kill the cancer  Cancer cells can be killed by Magforce nono theroperies, Nano xray therapies eliminating painful side effects of chemotherapy;loosing hair, hearing, etc..  Destroying tumor without killing healthy cells  No addition of toxics to body
  • 13 F UTURE TREATMENTS CONT …  New formulations and routes for drug delivery, optimal drug usage. (High consumption, lower side effects, cost and suffering)  ‘Gene gun’ that uses nanoparticles to deliver genetic material to target cells  Tissue engineering: More durable, artificial tissues and organs  Bones can be regrown on carbon nanotube scaffolds  Sensors for early detection and prevention
  • 14 N ANO E LECTRONICS AND C OMPUTINGPastShared computing thousands of people sharinga mainframe computer Present Personal computing Future Ubiquitous computing thousands of computers sharing each and everyone of us; computers embedded in walls, chairs, clothing, light switches, cars….; characterized by the connection of things in the world with computation.
  • 15 A PPLICATIONS CONT..  Cleaning- Super washing machines, Nano materialized clothes with special properties, Eg: Super hydrophobic  Security- Nano sensors, high security uniforms: Institute for Soldier Nanotechnologies (ISN) at Massachusetts Institute of Technology  Energy- Advanced Solar panels (24 hours working), fossil fuel replacements with high efficient cells  Many more…
  • 16 N ANO MANUFACTURING• Carbon Nanotubes• Nanostructured Polymers• Optical fiber performs through sol-gel processing of nanoparticles• Nanoparticles in imaging systems• Nanostructured coatings• Ceramic Nanoparticles for netshapes.
  • 17 N ANOTECHNOLOGY IN SPACE  Improvements in shuttle  Lighter weight and smaller in size  Nano sensors and Nano robots  Use of laser sails  Micro and Nano rovers for planetary exploitation  Benefits to Astronauts  Nano suits, Nano food : No refrigeration, Protection from bacteria and diseases, Lighter.  Cheaper space flights  Nano satellites  Will be 90% lighter, Greater Strength, Greater Safety margin due to Dimondiode fibers.
