Imagine a small creature inside of you that can detect when something ails you. It can diagnose the problem and eliminate it, if needed.
Well, that might not be too far off. Scientists, such as Richard Feynamn, who created the idea of nanotechnology based on the thought of putting the encyclopedia on the head of a pin back in 1959, have been working on the idea to benefit health and the environment.
They have the capability to build materials on a Nano-scale, such as computer chips and toxic gas detectors, and hopefully can harness the power of nanotubes to build a space elevator.
But with all of this progress there are always a few setbacks. Some environmentalists are causing a bit of a huff about the negative aspects of using Nanonmatter to build. Experimenting on rats and mice was found to cause complications in their lungs, futurist, K Eric Drexler, fears a future of nanobots replicating themselves to the point of digesting all life on earth to a grey goo.
But the experimentation does have its benefits. With the growing knowledge of Nanotechnology we could advance modern medicine by planting “smart bombs” that know where to knock out an illness, seek and destroy tumors, or even cure cancer.
This is a science that has also brought about the catalytic converter, which has detoxified engine fumes all over the world, and hopefully in the future, can lead to more efficient batteries and advancements in solar power.
Fortunately, in 2003, an independently commissioned report from Green Peace acknowledged the risks of nanotechnology, but hopes the field could generate significant innovations to benefit the environment.
