This week’s topic
really helps me to understand more about the nanotechnology, and I am extremely
interested in this topic. Nanotechnology is a word I always hear, but I don’t
really know what it is, and I think it is a modern technique that just
scientists need to deal with. Professor James K. Gimzewski’s lecture shows me a
new world of Nanotechnology, and he states that nanotechnology products are
actually common in the daily life. We can even see nano particles in materials
in pottery from the Renaissance period. By using nanotechnology, scientists use small balls to show chemical atoms.
Nanotechnology
helps us to improve our lives, and we can use our artistic creativity in a new
way. Nanotechnology helps to make tiny, abstract matter visible, and it helps
us to study nano particles which are very small. Nano particles can be used in a
lot of different industries such as electronic, biomedical and so on. Nano particles are more reactive than other molecules, and people use this characteristic to
benefit our life. For example, people use nano particles of iron to clean up
chemicals in the underground water. Besides, the lecture shows the lotus leaf
effect which helps people create surfaces of treatment that can stay dry.
Nanotechnology can
also potentially hurt people if we over use it. Nanotechnology is applied in
food and cosmetics. Nano particles can make food more delicious, and it can also
color the food. However, if the manufacturer over use nano particles, it can
hurt our health. Cosmetics is another example, some cosmetic products with nano particles will damage people’s skin and aquatic ecosystems.
In this week’s
lecture, I know that Nanotechnology is not that far away from my daily life. In
my personal point of view, I do believe people can definitely benefit from the
Nano technology. However, we need to avoid over use Nanotechnology which will
hurt us.

Hi, Junyi! I enjoy reading your blog because you can show both benefits and risks about Nanotechnology! As you, I am impressed Nanotechnology is very closed to our daily life. From Renaissance period, people have been using Nanotechnology. It means that human cannot live without Nanotechnology. "We can use our artistic creativity in a new way." As you said, we can discover new world by Nanotechnology, so I hope that people can control Nanotechnology and reduce the risks!
