Itty-Bitty Technology; Big Potential

Think about the size of a lady bug. Now, think 1,000 times smaller than that, and we’re talking about the size of a red blood cell. Go another 1,000 times smaller, and that’s how big a nanometer is. What can you do with something that small? We’ll find out this hour on Focus.

Nanotechnology works to understand the physics, chemistry and biology of nanoscale objects. Simply put, it’s the study of things that are very, very, very small. This hour on Focus, we’ll talk about nanotechnology and developments being made when it comes to nanomanufacturing here at the University of Illinois in Urbana-Champaign. Irfan Ahmad, Executive Director of Nanoscale Science and Technology at the UIUC and Engineering Professor Placid Ferreira, who studies nanotechnologies and manufacturing, will be here. We’ll talk with them about how certain elements behave quite differently on the nanoscale than they do in larger quantities and how that opens the doors to virtually limitless possibilities. Cell phone in a made to order size? It’s could happen.

There are also health concerns and risks many are worried about when it comes to using nanotechnology. We’ll talk those over too during this hour on Focus.
