Nanotechnology has been around for millennia in many different forms, from ancient pottery to
modern sun screen; it is even found in the wings of butterflies. But only recently is its full potential
being realised in what many are referring to as the ‘next industrial revolution’. Nanotechnology is
the manipulation of objects at atomic level, potentially enabling scientists to do almost anything
from building object atom-by-atom, to diagnosing and treating different diseases before the
symptoms even begin. Nanosensors could be placed in the body and detect rises or falls in blood
pressure or blood sugar, helping people with heart conditions or diabetes. Nanobots could be used
to deliver drugs and other treatments to the specific areas where they are needed. This could be
especially beneficial for treating different cancers, offering a more efficient and efficacious
alternative to radiotherapies. Nanotechnology would even make it possible to artificially
strengthen bones and muscles.

But of course there are problems and for the possibilities, nanotechnology faces much adversity.
Some research has found that carbon nanotubes, which are used in some products today, can
behave like asbestos due to their size. Because they are so small, the nanoparticles can be inhaled
into the lungs or absorbed into the skin, possibly causing or increasing the risk of cancer. There is
also the matter of privacy. Nanosensors could monitor our most personal information, so who
would have access to this information? Should nanotechnology ever prove to be cost effective?
Will only the richest have access to its benefits? Nanotechnology may never become as powerful
and prolific as envisioned by its evangelists, but as with any potential, near-horizon technology the
possible benefits are almost endless – as are the risks.
