  • describes engineered nanosystems (nanoscale machines) operating on the molecular scale. Molecular nanotechnology is especially associated with the  molecular assembler , a machine that can produce a desired structure
  • A mouthwash full of smart nanomachines could identify and destroy pathogenic bacteria while allowing the harmless flora of the mouth to flourish in a healthy ecosystem. Further, the devices would identify particles of food, plaque, or tartar, and lift them from teeth to be rinsed away. Being suspended in liquid and able to swim about, devices would be able to reach surfaces beyond reach of toothbrush bristles or the fibres of floss. As short-lifetime medical nanodevices, they could be built to last only a few minutes in the body before falling apart into materials of the sort found in foods (such as fibre).
  • Medical nanodevices could augment the immune system by finding and disabling unwanted bacteria and viruses. When an invader is identified, it can be punctured, letting its contents spill out and ending its effectiveness. If the contents were known to be hazardous by themselves, then the immune machine could hold on to it long enough to dismantle it more completely.
  • Nanobots are delivered to produce a lethal blow to a cancerous cell for destructing effectively by killing it. Once it has delivered its lethal blow, the nanoparticle breaks down into tiny pieces that get eliminated by the body in the urine. kill  cancer cells  in human patients using a new  RNA interference (RNAi) therapy  delivered via a special nanobot.  This nanobot targets the messenger RNA (mRNA)  to stop the production of  protein  in the cancer cell, thus starving the  cancer  from its source of survival.

    CONTENTS
  • What Does Nanotechnology Mean?
    • Nanotechnology is the engineering of   functional systems at the molecular scale.
    • It is the study of manipulating matter on an   atomic   and   molecular   scale.
  • NANOROBOTS
    • A nanorobot is a tiny machine designed to perform a specific task or tasks repeatedly and with precision at nanoscale dimensions, that is, dimensions of a few  nanometer s (nm) or less, where 1 nm = 10 -9  meter
    • They are nanodevices that will be used for the purpose of maintaining and protecting the human body against pathogens.
  • Molecular Nanotechnology (MNT) The umbrella science of nanomedicine
    • MNT describes engineered nanosystems (nanoscale machines) operating on the molecular scale.
    • MNT is especially associated with the   molecular assembler , a machine that can produce a desired structure.
    • MNT IS based on the ability to build structures to complex, atomic specifications by means of   mechanosynthesis .
    • What is a Chromallocyte?
    • What is a Respirocyte ?
    • What are the Risks of Nanoscience?
    • What are the Potential Benefits of MNT (Molecular Nanotechnology)?
    • What are the Potential Dangers of Molecular Nanotechnology ?
    Related wise GEEK articles
    • A chromallocyte is a lozenge-shaped mobile nanorobot , consisting of about four trillion atoms.
    What is chromallocyte?
  • Chromallocyte in Chromosome Replacement Therapy
    • A respirocyte is an engineering design for a machine that cannot be built with current technology: an artificial red blood cell a micron in diameter .
    What is Respirocyte?
  • Respirocytes in the bloodstream
    • Uncontrolled nanomachines
    • Nanoweaponery
    What are the risks of Nano science
    • Molecular nanotechnology (MNT) is a breakthrough science that combines principles of chemistry, biology and physics to propose microscopic devices on the nano-scale that would mechano chemically manipulate individual atoms and molecules for the purpose of constructing materials, eradicating disease, and restoring the environment; thus making the potential benefits of MNT wide-ranging and revolutionary.
    What is the potential Benefits of MNT?
    • ABUNDANT CLEAN ENERGY
    • ENERGYERADICATING DISEASE AND EXTENDING LIFE
    • HEALING THE ENVIRONMENT
    • SMART MATERIALS AND GREEN MANUFACTURING
    • HELPING THIRD WORLD NATIONS
    • COMPUTER MINIATURIZATION AND AI
    • SPACE COLONIZATION
    To Name just a few potential benefits of MNT
    • NANOWEAPONRY: THE NEWARMS RACE
    • ENVIRONMENTAL IMPACT AND EXISTENTIAL DANGERS
    • ECONOMIC IMPACT
    • DANGERS OF REGULATION
    • UBIQUITOUS SURVEILLANCE
    • ARTIFICIAL INTELLIGENCE (AI) AND ROBOTICS
    What are the potential dangers of MNT?
    • The powering of the nanorobots can be done by metabolizing local glucose and oxygen for energy. In a clinical environment, another option would be externally supplied acoustic energy.
    • Other sources of energy within the body can also be used to supply the necessary energy for the devices.
    • They will have simple onboard computers capable of performing around 1000 or fewer computations per second. This is because their computing needs are simple.
    • Communication with the device can be achieved by  broadcast-type acoustic signaling

  • How Nanorobots Will Work The robot in this illustration swims through the arteries and veins using a pair of tail appendages.
  • Powering of nanorobots
    • The powering of the nanorobots can be done by metabolizing local glucose and oxygen for energy. In a clinical environment, another option would be externally supplied acoustic energy.
    • Other sources of energy within the body can also be used to supply the necessary energy for the devices.
    • They will have simple onboard computers capable of performing around 1000 or fewer computations per second. This is because their computing needs are simple.
    • Communication with the device can be achieved by  broadcast-type acoustic signaling.
    • Designers sometimes look at microscopic organisms for propulsion inspiration, like the Nanorobot flagellum on this e-coli cell.
    • Breaking up blood clots
    • Fighting cancer
    • Parasite Removal
    • Gout
    • Cleaning wounds
    Take two bots and call me in the morning
    • Devices working in the bloodstream could nibble away at arteriosclerotic deposits, widening the affected blood vessels.
    • Cell herding devices could restore artery walls and artery linings to health, by ensuring that the right cells and supporting structures are in the right places.
    • This would prevent most heart attacks.
    Treating arteriosclerosis
    • FIBRE OPTICS TECHNOLOGY : Utilized in endoscopic medicine.Fiber optic instruments are introduced into the body cavity through a tiny hole made on the body to either to investigate or treat and ailments.
    • LASER TECHNOLOGY : Laser technology is utilized in cataract surgery and removal gall bladder stones.
    • TELEMEDICINE : With these facility doctors in remote areas can benefit from the expertise of the specialist urban centers.
    • SOUND WAVES : Utilized in investigative and therapeutic ultrasonography. 
    • NUCLEAR RADIATION : Utilized in the treatment of cancer and in investigations like x-ray.
    Few potential applications
  • All of these current developments in technology directs humans a step closer to nanorobots and simple, operating nanorobots is the near future. Nanorobots can theoretically destroy all common diseases of the 2l st century thereby ending much of the pain and suffering. It can also have an alternative, practical uses such as improved mouthwash and cosmetic creams that can expand the commercial market in biomedical engineering. People can envision a future where people can self-diagnose their ‘own ailments with the help of nanorobot monitors in their bloodstream. Simple everyday illnesses can be cured without ever visiting the physician.
