Nanotechnology Uses and Potential Risks

Although still not so clear how this new invention will possibly directly affect the human body, its effects on the human health and in the health industry at large area already being experienced. Nanotechnology is widely being used in many hospitals. For instance, research is being done on a special type of nanoparticles which can help cure cancer by directly delivering the cancer terminating drugs to cancer cells in the body. Nanotubes are already being used since decades ago too. It is almost as if nanotechnology will have an effect on many health sectors and this only seems to have a positive effect on mankind on a large scale though not widely implemented.

It is also already clear that nanotechnology has a major effect on technology. Devices employing the use of microparticles are being deployed to use in every industry everyday.

One hugely potential dangerous effect of the advancement of nanotechnology is the possibility of nanobots evolving and developing their own artificial intelligence and thus overtaking the human race in the near decades, this is an almost sure possibility if the current advancements are not controlled. The evidence for this is that everyday scientists are coming up with more automated machines that can think or even perform some tasks out of their own thinking and thus there is this unfortunate possibility that they could use this intelligence to damage and threaten humans.

One last risk that nanotechnology poses is one of polluting the environment and this has lead to the establishment of some control bodies by governments and concerned organizations. The nanomaterials that are created in the process are known to kill some useful bacteria and this can alter the way ecosystems are run with much potential dangers.
