Nanotechnology is a
term I often heard but didn't realized what exactly it is. Through this week’s
lecture Dr. Gimzewski gave us a deep explanation of nanotechnology from its
history and applications. Nanotechnology has been revolutionizing the world of
art and technology for many years and it’s much more present in our lives
than we are aware of it. Many of our clothes , electronic products and even
food contain some elements of nanotechnology.
The silver
nanoparticles can destroy the bacteria effectively so it has a variety of applications.
For example, many sportwears like socks and underpants contain silver
nanoparticles that have an antimicrobial effect so you can wear them for a long
time without smelling bad. It can also be used in food packaging bag and other antibacterial
products.

One famous example of
applications of nanotechnology in our lives is Donna Srgo. Donna surge is an
Australian designer who created dresses with Morphotex fabric, an Nanotech-engineered
material. This material is structured to mimic the properties of Blue morpho
butterfly wings. Instead of getting its color by the pigment, this material
gets its color through its internal structure alone, resulting in pure color
which will never fade. It replaces the use of toxic dyes and will be better for
our environment and the human health.
We have found many applications of nanotechnology in the modern society, but actually nanotechnology
is not an entirely new technology emerging in recent several decades. We can also find nanoparticles in some ancient artistic works. The Lycurgus Cup from the Roman era of 400 AD appears jade green when you look at the cup in daylight and
appears red if you illuminate it from inside. This mystery puzzled scientists
for decades and wasn't solved until 1990. When scientists scrutinized broken
fragments under a microscope and discovered that the Roman artisans used
particles of silver and gold and grounded down them until they were as small as
50 nanometers in diameter. When metal such as gold and silver are broken down
into nanoparticles, their optical properties change because the way in which
the particle absorbs light wavelengths changes. Roman artisans are actually the nanotechnology
pioneers. The mysterious beauty of The Lycurgus Cup is a perfect example of combining
art and nanotechnology.
I am very surprised
that we are currently exposed to a lot of nanotechnology. Nanotechnology has so
many great features that fascinated me and I believe it will surely bring a lot
of more benefits to humans.
