Nanotechnology

What I know:

• Nanotechnology has been researched a lot in the last decade.
• It is very useful for governments and security agencies.
• It is very complex technology but also used for everyday life such as ipods, calculators and cellphones.
• Nanotechnology helps things be lighter and smaller but as powerful as big machines
• It has improved a lot in the last years for example in computers, they used to be huge but now they are small and light but still powerful.

What I want to learn:

• Who develops this technology
• Examples of some of this technology
• How it helps with health issues

Links:

• http://www.nanotech-now.com/news.cgi?story_id=46018 It explains how nanotechnology is used by health companies to cure different things and also to figure out what causes them.
• http://www.nano.gov/ It explains what nanotechnology is on the side and why it is useful to us.
• http://www.crnano.org/whatis.htm It explains a little bit more about nanotechnology the meaning of it and its organization.

What I learned:

• Nanotechnology is using molecules to build things the things built are very small and sometimes even smaller than a cell.
• Nanotechnology has found some spots in the DNA that decide whether you will or will not have the cancer gene.
• Thanks to nanotechnology a bio sensor was created to help diagnose if a person has cancer.
• Lots of things with the name nanotechnology are not actually nanotechnology because they are not built atom by atom.
• There are 4 generations of nanotechnology development, each of them is different and it goes from passive nanostructures to active nano structures to systems of nano systems to molecular nano systems. The order goes form least specified to more specific. The oldest one is passive nano structures and the newer one is molecular nano systems.

How it Relates to my Life:

• It relates yo my life because in a uncertain future nanotechnology might take over the building of things. Things might be build from a molecular level so they can be more exact and specific so there is a shorter margin of error. I am interested in nanotechnology because it is the smallest way there is to build something. In the future everything might be made by nanotechnology so it involves everyone.

Questions I still Have:

• Why is nanotechnology so important and why do people want things to be built from atoms not normal building blocks.
• What things that we might use might be created from this technology.
