Every day we are traveling to a new era of
technological developments, one of which and at the same time the most exiting innovation
is nanotechnology. Despite other benefits that come with this new area of
science the most important is in terms of medical treatments. This essay will
state the advantages and disadvantages of medical nanotechnology nowadays.
Nanotechnology behaves very diverse regarding
medical treatments, because it has a wide range of advantages and uses. To
begin with, nanotechnology can be used to transport medicine or drugs into
different parts of human body in a less harmful way, through tiny instruments
called nanoparticles. Some kinds of nanoparticles called the
“gold-nanoparticles” have resulted effective in the treatment of cancer because
of their ability to assimilate radiation. Once they enter inside the tumor
cells they assimilate the
energy and heat up until the cancer cell is killed. In addition, important
implementation of nanomedicine is in terms of surgery. Extremely small surgical instruments and even robots are used today to
perform microsurgeries with high preciseness, because they have nanocameras
within which allows the doctor to have a close up look of the whole process.
Furthermore, the visual dream of a
world free of viruses has finally come to a real thing with nanorobots which
are used as artificial white cells. They “hit and kill” a dangerous
pathogen via a microscopic laser device mounted on it. But the most incredible
invention on this field is undoubtedly the creation of artificial organs for implants.
They promise an increase in the quality of human life with less infections and
a prolonged lifetime. Until now there has been generated a human heart from steam
cells, but this technology promises even more in the future.
On the other hand even though there
are so many benefits from this new field of technology people still seem to be
skeptical because of the potential risks it might have. When speaking of risks
every new invention has its other side of the coin. Firstly, nanoparticles can
be plugged in our body through skin, breathing routes and digestion or injected
intentionally enough easier than most particles. If they can’t be broken down
and digested or degraded, there is a danger they will gather up and damage
organs. Secondly, we don’t know exactly how nanotechnology co-operates with
biological systems. They could learn to reproduce themselves and act in the
same way as viruses and bacteria.
Thirdly, there is a risk of
neuronal translocation. If these nanoparticles intersect with the brain, they
can cause translocation of inhaled particulates to the brain. Moreover, the
plutonium artificial heart made of these nanoparticles may be risky for the
health and environment if not transplanted in the proper way. Plutonium is a
toxic material and it should be treated very carefully during surgeries or it
will be lethal for the person.
In conclusion, nanotechnology is a very tangible topic all over the
world today. It has a lot of advantages from medical treatments to artificial
organs implants as well as minor drawbacks which need to be solved. But in my
opinion the future years will be a blast of this innovation not only in the
medical field but in all activities related to human life.
