  3. 3. NANOTECHNOLOGY OVERVIEW<br /><ul><li>HISTORY OF NANOTECHNOLOGY
  4. 4. DEFINITION OF NANOTECHNOLOGY</li></li></ul><li>NANOTECHNOLOGY OVERVIEW<br />HISTORY OF NANOTECHNOLOGY<br /> - Moore’s Law<br /> - Development of nanotechnology since 1965 <br />
  5. 5. NANOTECHNOLOGY OVERVIEW<br />DEFINITION OF NANOTECHNOLOGY<br />First what is Nano?<br />Nano - A prefix<br />- From Greek word náno - meaning dwarf<br />- Extremely small<br />- In the names of units of measure – one billionth<br />-Nano meter scale - one billionth of a meter ( x10-9 m. )<br />
  6. 6. NANOTECHNOLOGY OVERVIEW<br />
  7. 7. NANOTECHNOLOGY OVERVIEW<br />What is Technology?<br />Technology – the branch of knowledge that deals with creation in the fields of :<br />- Engineering<br />- Industrial arts<br />- Applied science <br />- Pure science<br />Now what is Nanotechnology?<br />- The engineering of functional systems at a molecular scale<br />- The manipulation of the structure of matter at the molecular level<br />- The “bottom up” approach of building materials from a nanometer scale using techniques and tools being developed today to make complete, highly advanced products. <br />- Basically mean small technology<br />
  8. 8. NANOTECHNOLOGY IN ENGINEERING<br /><ul><li>NANOMACHINES
  9. 9. NANOBOTS</li></li></ul><li>NANOTECHNOLOGY IN ENGINEERING<br />2. 1 NANOMACHINES<br /> I-switch<br />- ADNA nanomachine<br />- Externally triggered by protons <br />- Based on fluorescence resounance energy transfer(FRET)<br />- Functions as a pH(a measure of acidity) sensor<br />
  10. 10. NANOTECHNOLOGY IN ENGINEERING<br />Drosophila cells with the I-switch inside their endosomes.<br />I-switch mapping out spatial and temporal pH changes associated with endosome maturation.<br />
  11. 11. NANOTECHNOLOGY IN ENGINEERING<br />Nanoimpellers<br /> - Nanotubes made of light-sensitive silica<br /> - Carries cancer-killing drugs<br />- Targets only cancer cells<br />- Injected into human cancer cells in vitro <br />How does it work?<br /> When light strikes the silica<br />- Tiny tails inside the tubes wag back and forth<br />- Creates a current that releases the drugs out of the tube<br />
  12. 12. NANOTECHNOLOGY IN ENGINEERING<br />A cancer cell culture from a kidney tumour is shown. <br />
  13. 13. NANOTECHNOLOGY IN ENGINEERING<br />2.2 NANOBOTS<br />Mechanical Nanobots<br />Consists of:<br />- Head<br />- Two arms<br />- Two legs<br />Fictional Nanobot<br />
  14. 14. NANOTECHNOLOGY IN ENGINEERING<br />Biological Nanobot<br />Nanobot Made of Bacteria<br />- Can be injected with catheter<br />- Can be guided with magnetic field<br />- It’s purpose is to deliver a toxic<br />payload<br />
  15. 15. <ul><li>WAYS OF IMPROVEMENT
  16. 16. NANOELECTRONICS APPLICATION</li></ul>NANOTECHNOLOGY IN ELECTRONICS<br />
  17. 17. NANOTECHNOLOGY IN ELECTRONICS<br />3.1 WAYS OF INPROVEMENT:<br /> - Reduce the weight and power consumption.<br /> - Improve display screens on electronics devices.<br /> - Increase the density of memory chips.<br /> - Reduce the size of transistors used in integrated circuits.<br />
  18. 18. NANOTECHNOLOGY IN ELECTRONICS<br />3.2 NANOELECTRONICS: APPLICATIONS UNDER DEVELOPMENT<br /> - Building transistors<br /> - Using electrodes made from nanowires<br /> - Developing molecular-sized transistors<br /> - Using nanosized magnetic rings<br /> - Usage of carbon nanotubes<br />
  19. 19. <ul><li>DRUG DELIVERY
  20. 20. THERAPY TECHNIQUES
  21. 21. ANTI – MICROBIAL TECHNIQUES</li></ul>NANOTECHNOLOGY IN MEDICINE<br />
  22. 22. NANOTECHNOLOGY IN MEDICINE<br />4.1 DRUG DELIVERY<br /> - Employing nanoparticles to deliver drugs.<br /> - Oral administration of <br /> drugs.<br />
  23. 23. NANOTECHNOLOGY IN MEDICINE<br />4.2 THERAPY TECHNIQUES<br /> - Buckyballs<br /> - Nanoshells<br /> - Nanoparticles<br /> - AluminosilicateNanoparticles<br /> - Nanofibers<br />
  24. 24. NANOTECHNOLOGY IN MEDICINE<br />4.3 ANTI-MICROBIAL TECHNIQUES<br /> - Nanoparticle Cream - Nanocapsules<br /> - Cell repairs using Nanorobots<br />
  25. 25. SUMMARY AND CONCLUSION<br />- From being a theory to something we can now see, words turned into reality.<br />- Nanotechnology has evolved over the period of time for many decades, and is now showing its potential to the whole world. <br />- The development of nanomachines such as: I-switch, nanoimpellers, nanobots etc.<br />- Nanotechnology will increase your standard of living.<br />- Up to today nanotechnology is what's in, what's new, and what's the latest technology being developed all over the world. <br />
