[SOLVED] The Sunscreen Effectiveness

Prior to taking this course, had you ever heard of nanotechnology? Now that you know more about it, can you think of ways in which this type of technology can have an impact on your life?Please include the name of the person or question to which you are replying in the subject line. For example, “Tom’s response to Susan’s comment.”ALSO PLEASE REPLY TO ANOTHER STUDENTS COMMENT BELOW WITH A POSITIVE COMMENT RESPONSEPATRICK: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.
