“The principles of physics, as far as I can see, do not
speak against the possibility of maneuvering things atom by atom” – Richard
Feynman
Before the term nanotechnology was even conceptualized, Feynman
in his 1959 lecture “There’s Plenty of Room at the Bottom,” was already hinting
at a field that as Professor Victoria Vesna states, “will push us over the edge
into the 21st century.”
Other than the two experimental developments that put
nanotech on the map: Scanning Tunneling Microscope & Atomic Force
Microscope, what I found most interesting of this unit was the manipulation and
utilization of nanoparticles which were found to be versatile in applications,
tech and medicine.

Although it may not be evident, nanoparticles provide
coloration showing an example of the intersection of nanotech + art. Another
instance where the intersection is clear is stained glass in churches.
Interestingly enough, stained glass cannot be achieved using other color
pigments.

As Professor Gimzewski pointed out in the lecture videos,
there are only 1000 nanoproducts (estimate during the time of lecture
production) and by 2015 the world market for products that contain
nanomaterials is expected to be $2.6 trillion. There is a lot of investment going into the
research and development of this field.
Here we see how nanotech is becoming pervasive in our life.
Nanotech allowed for the emergence of “Nano-cosmetics.”

This image above shows other uses for nanoparticles such as
bacteria and odor-eliminating features as found in Nanosilver particles.
L’Oreal has been a prominent leader in the field of
“nano-cosmetics.” It was discovered that through nanotechnology, one could
obtain every spectrum of color and thus companies can replace cosmetic products
that contain carcinogenic material.

There is still work and research to be done in this field,
as people are worried about their safety. Once concern is that nanoparticles
may penetrate human organs. Also, nanoparticles have been noted to be found in
some food so this raises other concerns. Maybe their fears stem from the lack of visibility.
When you think about it, how can something that is practically invisible, be so influential in medicine, technology, art and cosmetics!

Hi Jaime,
ReplyDeleteI really enjoyed reading your post! My favorite example you used was the one with nano-cosmetics. It was interesting to hear that so much money is being poured over to research and development to find new discoveries in this field. I remember the make-up brand, Almay, was one of the first to pioneer the nano-cosmetic idea. They advertised it as a way to color blend into your natural skin color. Thanks for posting!
Best,
Ariel Jao
