Live A Long Life – Swallow A Nanobot

by Malc on November 3, 2008

nanobot_1 Living a long life will be much easier as we develop ‘nanobots’ with the ability to travel within our bodies. These will be programmed to carry out various tasks.

Nanobot Tasks

Some of these will be:

  • Delivering drugs to precise locations – for example, direct to disease locations, rather than in the blood stream. Treatment will be more accurate and have fewer side-effects and so make long life more likely.
  • Docking with pathogenic cells to disable them. For example, a previous post looked at treatment of cancer cells by using nanobots combined with a protein cell to dock with the cancer. The cancer cells would then be drawn to the body surface with magnetism and destroyed.
  • Micro surgery. For example, nanobots will be directed into the eyeball to carry out repairs without any incision being necessary.

Advantages of Nanobots For Long Life

The advantages of nanobots over conventional surgery will be huge. They include:

  • Reducing infections. Opening up the skin causes infections – this is why hospital is such a dangerous place to be. By avoiding cutting, infections are dramatically reduced.
  • Reducing cost. Because there are no, or fewer, open wounds, the chance of infection is much smaller. Expensive clean-room techniques and extreme infection control will just be unnecessary.
  • Reduced mortality. In other words, you will be more likely to survive an operation. The shock will be less; recovery faster as well as infection being much less likely, as mentioned.

Powering Nanobots

Robots have already been used in the gut; and moving them through presents no problem as the gut’s natural peristalsis does the job. However, to move a nanobot around out side the gut presents the problem of how to steer it.

Magnetism

One answer is to use magnetism. This will be satisfactory in some cases; and the magnetic fields are readily available in hospitals already – in MRI scanners.

Magnetism is a little crude however.

Pizo-electricity

Another method which is being developed is to use pizo-electricity – the minute electric current produced by crystals in the presence of an electric charge. This will be harnessed and fed to flagellae – flailing corkscrew-like arms, which can be used for propulsion. This is how bacteria move.

Chemotaxis

A third way to move nanobots will be by using chemotaxis – by getting the nanobots to follow a chemical gradient. Then, by introducing chemicals, the bots could be steered.

Future Life Is Long – And Will Be longer

Longer life is already with us. Every decade the average lifespan is increasing by several years.

Nanobots will certainly help to ensure that this process continues. In 10-20 years many surgical operations will be being carried out completely internally. There will be no external surgery, minimal trauma, minimal side effects, fewer drugs used and a rapid recovery.

As the technology improves the changes will be incremental, producing surges of medical advancement which will probably stagger many of us within one or two decades.

    can we emulsify human cataracts with help of nanorobots?

    Hi

    Good question. No idea – anyone?

    Cheers
