I have briefly heard about nanotechnology prior to this course but never had an understanding of what it mean, I figured it meant small due to the phrase nano being incorporated. It is a pretty interesting concept, especially when looking at it from a medical side, as the reading mentioned they want medicine small enough to penetrate certain barriers but no capable enough to cause brain damage. To me it is interesting there is that line where the technology goes from being beneficial to harmful. I think the main common item that utilizes nanotechnology, which I am sure most of us will utilize soon due to summer coming, is sun screen. Sun screens contain many different components with two nanoparticles being added to increase the sunscreen effectiveness; titanium dioxide and zinc oxide.
