Transcript of "Nanorobots"

  1. 1. NaNotechNology aNdmediciNePresented by:C.SIVA GAYATHRIB.VEDAVAHIP.PRAVEENA
  2. 2. NaNo scieNceThe prefix “ nano” is a Greek word for “dwarf”One nanometer (nm) is equal to one-billionth of ameterAbout a width of 6 carbon atoms or 10 water moleculesA human hair is approximately 80,000 nm wideRed blood cells is 7000 nm wideAtoms are smaller than 1 nanometer Molecules and some proteins are between 1 nm andabove
  3. 3. NaNo scieNceAt IBM in the US, a technique called electron beamlithography was used to create nanostructures and devicesas small as 40 to 70 nm in the early 1970s
  4. 4. NaNo scieNceThe concept of nanotechnology was first coined by RichardFeynman in 1959 in his lecture “There’s plenty of room atthe bottom”Manipulating material at a scale of individual atoms andmoleculesImagining the whole Encyclopedia Britannica written onhead of a pin
  5. 5. NaNotechNology iNmediciNeNanotechnology is a new field with many possible uses,medicine being one of them
  6. 6. NaNo techNology“The manufacturing technology of the 21stcentury"The study and manufacture of devices of moleculardimensions, in the range of nanometers or one-billionth of a meterMost of industrial manufacturing processes arebased on top-down technologies -- i.e., they takelarger objects and make them smaller yieldingproducts of fairly high precision and complexity
  7. 7. NaNo techNologyDNA serves as a data-storage system, transmittingdigital instructions to molecular machines e.g., theribosomes, that manufacture protein molecules.
  8. 8. NaNo mediciNeSome medicines are made through biotechnologicalprocesses, for example those using recombinant DNA(human hepatitis vaccine)Under these processes the DNA of living creatures(usually bacteria) is alteredNanotechnology represents a similar approach to themanufacture of pharmaceuticals and other goods.
  9. 9. NaNo robots: mediciNe of thefutureWhat are they?Nano robots are nano devices that will be used for thepurpose of maintaining and protecting the human bodyagainst pathogens.They will have a diameter of about 0.5 to 3 microns andwill be constructed out of parts with dimensions in therange of 1 to 100 nanometers
  10. 10. NaNo robotsThe powering of the nanorobots can be done bymetabolizing local glucose and oxygen for energyOther sources of energy within the body can also beused to supply the necessary energy for the devicesThey will have simple onboard computers capable ofperforming around 1000 or fewer computations persecond.
  11. 11. NaNorobotsA navigational network may be installed in the body,which may provide high positional accuracy to allpassing nanorobotsThis will enable the physician to keep track of thevarious devices in the body
  12. 12. “A microscopicmachine roamingthrough thebloodstream,injecting or takingsamples foridentification anddetermining theconcentrations ofdifferentcompounds"
  13. 13. A singleinhalednanorobotreaches,deeplyinspired intothe lungs,enters analveolar ductand attachesto the tissuesurface.
  14. 14. Mechanicaldrilling of asmall tumormass by ananorobot
  15. 15. TherapeuTic applicaTions ofnanoTechnology in MedicineNanotechnology also theoretically allows the mimickingof natural biological processes e.g., repair of damagedtissuesUsing nanotech to build scaffoldings of artificialmolecules that bone cells often adhere to and growbones onBroken bones would heal much faster.Transport of oxygen within the body by creating anartificial red blood cell
  16. 16. TherapeuTic applicaTions ofnanoTechnology in MedicineTo cure skin diseases, a cream containing nanorobotsmay be used it may:- Remove the right amount of dead skin- Remove excess oils- Add missing oils- Apply the right amounts of naturalmoisturising compounds- Achieve the elusive goal of deep pore cleaningby actually reaching down into pores andcleaning them out.
  17. 17. TherapeuTic applicaTions ofnanoTechnology in MedicineA mouthwash full of smart nanomachines could identifyand destroy pathogenic bacteria while allowing theharmless flora of the mouth to flourish in a healthyecosystem
  18. 18. Four remote-controlled nanorobots examineand clean the subocclusal surfaces of apatients teeth, near the gumline.DentalRobots
  19. 19. TherapeuTic applicaTions ofnanoTechnology in MedicineMedical nanodevices couldaugment theimmune system byfinding anddisabling unwantedbacteria andviruses.
