NANOTECHNOLOGY

NANOTECHNOLOGIES

How do you think nanotechnology

might affect people's lifestyles?

I think nanotechnology might affect our lives in many ways. Because these things are so small, they can be used in ways that were never thought possible before. Scientists will be able to develop new technology for all kinds of things around the home, office and even for use in the medical field.

transportation: cars and planes safer and more efficient/ stronger due to lighter materials/less fuel needed/faster/ easier to operate

consumer products: cleaning materials safer and more efficient/self-cleaning glass and fabrics save time and money

environment: fewer chemicals/less need for fossil fuels/ drinkable water

food: hunger wiped out/genetically-engineered crops/ more wheat, fruit, vegetables and animal food sources/

better quality

medicine: improved diagnosis/ early detection and treatment/drugs directly injected into bloodstream/ faster, more positive results/cure or control of many diseases

1. There are many potential dangers with nanotechnology.

2. Doctors can often remove cancerous tissue from patients.

3. What was once only read in science fiction is now a reality.

4. Scientists are hoping to improve methods of fighting disease .

5. Cars with better fuel efficiency are better for the environment .

6. A foreign body is something in the body that shouldn’t be there.

7. Some scientific theories suggest that this may reduce global warming .

8. The craftsmen use traditional materials such as wood and stone.

9. We are hoping to prevent an environmental catastrophe .

10. Scientists must use extreme caution with this new technology.

11. Skin is a natural barrier against infection in the body.

12. Biological membranes cover our cells and help protect them.

• may cause DNA mutations
• may be harmful to the environment

Nanotechnology will most definitely change people’s lives. The question should be whether it will change our lives for the better.

I think the research needs to be further developed before an actual decision is made on whether this technology is the scientific break-through it appears to be. If it can actually do all of the things scientists believe it can do, then I think it will be amazing.

However, we must be cautious not to start using this technology before we know all of the risks and possible dangers.
