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.
MEDICINE OF THE FUTURE
POOJITHA CHINTHALA Roll no:12080026 Priyadarshini College of Pharmaceutical Sciences NANOROBOTS Presented by
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 .
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.
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.
