Development in Nanotechnology
Reply to:
1. What is the one example of development
in science and technology that man
brings about?
2. Give a description of this development in
less than 200 words. In your description,
explain how man has altered the living
and non-living factors in the ecosystem
to bring about this development.
How does this benefit us?
With nanotechnology, we can now find ways to save lives.
We can make drug delivery vehicles to deliver the exact
amount of drug required to do specific organ so as to
reduce side-effects of the drug. It can also be used to
engineer tissues and regrow bones.
It also allows us to make new materials with the
properties we need, allowing us to manufacture new
things.
Nanotechnology allows us to filtrate water and make it
cleaner for us.
They may be used to clean up nuclear waste, reduce
energy consumption, or increase energy production.
They are placed in foods so that it makes the food more
healthy for us.
Impacts on the environment and
ecosystem
Positive
1. Potential nuclear waste cleaning agent.
2.
Negative
1. Potential health hazards if nanomaterials
are exposed to organisms.
2.
