WEEK 8: NANOTECH AND ART
Nanotechnology is a field of incredible potential. It is
surprising that a field such as nanotechnology, which has revolutionized all
aspects of our life, from food to our clothes to medicines, is known so little.
It was fascinating to see the mere number of subfields that have been created
under the umbrella of nanotechnology, such as nanomedicine, nanoelectronics and
nanophotonics.
One of the most surprising examples of use of nanotechnology
by the Romans in the Lycurgus Cup. The cup will appear green when lit from
front, but if it were lit from the back it would change color to red. This
change in color happens due to presence of gold and silver particles that are
50 nanometers in diameter. The fact that romans were able to do this 1600 years
ago is absolutely amazing.
Furthermore, nanotechnology is also present in nature. The
wings of the Blue morpho butterfly seem to have a blue iridescent color but are
in fact transparent. Their wings consist of many nano-scale structures with air
in between then, which cause the light waves to diffract and undergo
constructive interference to give the blue color to the wings.
However, the one subfield of nanotechnology that caught my
attention was nanomedicine. A great example of its benefits can be seen the
research undergoing at University of Liverpool on use of nanotechnology in
treating HIV. The current treatment is oral dosing of HIV drugs which cause
significant health complications due to taking so many pills. One way
nanotechnology could help is since cells absorb it more easily it can reduce
both the does and the cost of the dose. This will make the treatment safer and
more accessible.
However, nanotechnology comes with its problems. As Dr.
Gimzewski pointed out, the long-term effects of nanoparticles haven’t been
tested rigorously yet. Since these particles are able to penetrate cells more
easily they regular medicines, it could cause a lot of harm. In 2011, the
global nanomedicine market was estimated to be worth $50.1 billion. It is
estimated that the market would grow to $350.8 billion by 2025. This
exponential growth is not healthy for a field that we are not knowledgeable
about. There is a need to proceed with extreme caution.

I thought your section on the blue morpho butterfly was very interesting because I would never think nanotechnology would be evident in nature. This leads me to believe that we can learn a lot from organisms in nature and we can study their molecular structures to develop new scientific studies. I also thought the nanomedicine was a crazy concept because a lot of money and resources will be saved if nanomedicine is funded. Great post overall.
ReplyDeleteI really liked your post this week! It was very interesting nanotechnology is in all aspects of our lives every day. Something that I never heard of that I found really interesting is when you talked about the Romans and the Lycurgus Cup. The fact that this was done so long ago it quite amazing and I feel like we don't recognize more stuff like the Lycurgus Cup. Overall, I really liked reading your post.
