Did that attract your attention? Scientists at IBM using a very powerful microscope took a picture of a molecule. That might not seem like much but we are talking about a picture where you can ‘see’ things that are less than a nanometer. The molecule is pentacene which is important for organic transistors. Those are switches made of things that aren’t like the current ones which are made from silicon. Pentacene is a hydrocarbon, so a bunch of carbon atoms arranged in rings. The microscope that they used is an atomic force microscope which doesn’t have a lens but has a very sharp tip. On the tip these scientists put a molecule of carbon monoxide. The carbon monoxide as it was dragged across the pentacene interacted with it and the result is a picture of pentacene. Is this useful? For sure. Useful for making tiny transistors out of single molecules. (for more info go to www.ibm.com)
