Advances in medical nanotechnology

Advances in medical nanotechnology depend on our understanding of living systems. With nano-devices, we would be able to explore and analyze living systems in greater detail than ever before. Autonomous molecular machines, operating in the human body, could monitor levels of different compounds and store that information in internal memory. They could determine both their time and location. Thus, information could be gathered about changing conditions inside the body, and that information could be tied to both the location and the time of collection.
These molecular machines could then be filtered out of the blood supply and the stored information could be analyzed. This would provide a picture of activities within healthy or injured tissue. This new information would, in turn, provide us with deeper insights and new approaches to curing the sick and healing the injured. Nano-robots could help us to change our physical appearance. They could be programmed to perform cosmetic surgery, rearranging our atoms to change our ear/nose shape, eye colors or any other physical feature we wish. These are all the possibilities with nanotechnology.
Super medicine:-
If we combine microscopic motors, gears, levers, bearing, plates, sensors, power and communication cables, etc with powerful microscopic computers, we will have a new class of materials. Programmable and microscopic, these smart materials could be used in medicine.
For example, medical nanite could patrol the body, armed with the complete knowledge of a person’s DNA, and dispatch any foreign invader; such cell sentinels would form immunity to not only the common cold but also AIDS and any future viral or bacterial mutation. These nanites would do what the plastic surgeon does, but in a better way. No pain, no bruising and results over night. People would be able to sculpt their own bodies. These who feel they were born the wrong sex could take on the full reproductive attributes of an opposite sex. So men could bear children.
How about painless childbirth? With mature nanotechnology capable of cellular manipulation, there is no reason a women should experience torturous hours of labour for that miraculous moment of birth. Trauma is not a great way for the newborn to enter the world either. Birth will not be traumatic with nanotechnology. Dilation can be controlled by the mother without pain.
Life extension:-
A finch lives two years, a parrot ninety, a gecko one year and a Galapagos Island turtle two hundred. The difference is the genetic programming. The geneticists are quickly unraveling human genetic code. Life is molecular machinery, with atoms arranged in dynamic complex relationships, controlled by DNA. If we have tools small enough to work on a machine and understand its controlling software, machines and their behavior can be modified. Even without nanotechnology, genetic therapies for stopping aging and even reversal will be developed soon.
Cryonics-raising the dead:-
When a patient’s heart stops beating, but before the structure of his brain starts to degenerate, the patient is attached to heart-lung machine and progressively infused with ‘anti-freeze’ and other cellular stabilizers and then his body temperature is lowered until the patient is at liquid nitrogen temperatures. At this point, all molecular stops indefinitely and the patient is put in storage. Later, when nanotechnology cell repair devices become available, the fatal disease that caused ‘death’ is reversed, the anti-freeze toxicity is removed; the patient is warmed back up alive and well.
