Bionanotechnology from nature

  1. 1. Bionanotechnology from Nature <br />Bionanotechnology from Nature <br />
  2. 2. Lessons From Nature<br /><ul><li> Nature is master of bionanotechnology
  3. 3. Nature depicts how soluble molecules are able to recognize and bind to specific materials to shape into nanostructures
  4. 4. Nature offer functional proteins and many other compounds at cellular level of great significance to life on earth.
  5. 5. Natural biomolecules such as DNA, proteins, peptides, lipid, carbohydrates act as templates to arrange inorganic substances such as metals on nanoscale</li></ul>Bionanotechnology from Nature <br />
  6. 6. Lotus effect<br />Lotus Effect<br /><ul><li> The lotus effect refers to superhydrophocity displayed by the lotus leafs
  7. 7. The effect is attributed to the micro-nano roughness of the structure surface of the lotus leaf and minimizes the surface area to 2-3% only
  8. 8. It further reduces the adhesion forces between the droplets and the leaf surface & rolls off from surface making it self cleaning & water resistant</li></ul>Bionanotechnology from Nature <br />
  9. 9. Lotus effect<br />Gecko Feet And Superglue<br /><ul><li> Gecko lizard has nanostructured hair which are 3-130nm in length and splits at the ends into tinerhooks
  10. 10. Gecko can climb smooth surfaces without falling due to its nanostructured body hair
  11. 11. The superglue ability of Gecko is similar to carbon nanotubes which can act like Gecko feet by extending microscopically from a surface and curve like a hook</li></ul>Bionanotechnology from Nature <br />
  12. 12. Lotus effect<br />Flow Sensors Based On Blind Fish Hair Structures<br />Bionanotechnology from Nature <br /><ul><li>Astyanaxis a blind fish but for its survival, it has developed hair on its body called cupula
  13. 13. The cupula is the eye of fish which can sense underwater hydrodynamic motion and is capable of detecting predators and prey
  14. 14. Inspired by this natural phenomenon, scientists have created artificial sensors similar to cupular structure which can sense movements better than blind fish itself!</li></li></ul><li>Lotus effect<br />Natural Bionanomachinery<br /><ul><li> Natural bionanomachines are made to function inside cells.
  15. 15. Bionanomachinesare designed to be stable when surrounded by water.
  16. 16. Bionanomachinescannot be designed or analyzed in other solvents or in vacuum, because they only show their true structure and function when placed in water.
  17. 17. The forces holding bionanomachines together are strong enough to build a stable structure despite the constant jostling of thermal motion and battering by water molecules.
  18. 18. The forces are weak enough to allow the construction and demolition of bionanomachines with modest energy resources. </li></ul>Bionanotechnology from Nature <br />
  19. 19. Lotus effect<br />Butterfly wings <br />Bionanotechnology from Nature <br />The bright color wings of butterfly are consequence of the nanotopography of the wing’s surface and its interaction with light. The resulting colors are quite striking and visible at a great distances.<br />
  20. 20. Lotus effect<br />Protein Folding<br /><ul><li>Nature uses an information-efficient method for construction of proteins
  21. 21. Natural proteins are designed to form stable globular structures
  22. 22. When the protein folds, the water molecules are released to form more favorable interactions with the surrounding water
  23. 23. The folded protein, lysozyme, is covered with nitrogen and oxygen atoms that carry electrical charges which form strong interactions with the surrounding water</li></ul>Bionanotechnology from Nature <br />
  24. 24. Viruses <br />Lotus effect<br />Bionanotechnology from Nature <br /><ul><li> A typical virus is between 10 to 300nm in diameter
  25. 25. Viruses are of particular relevance for bioscience because of</li></ul> their small size and similarity of some functions to molecular<br /> machinery<br /><ul><li> A virus particle with its protein coat, called viron</li></ul> form crystal like non-living molecular materials.<br />
  26. 26. Lotus effect<br />Bionanotechnology from Nature <br />Nano Science and Technology Consortium<br />A-105, Level-III, Sector-63, <br />Noida-201301, U.P., (India).  <br />For Queries/Concerns  <br />Tel: +91-120- 4781215-17 Mob:+91-9818206463  <br /> Website: www.nstc.in E-mail: info@nstc.in  <br /> Chat: Yahoo ID- nstcchat<br />
