Under the Microscope
Over 40 students crammed into Lab P4 to see Dr Colm Durkan’s excellent talk on Nanotechnology on Monday. He brought along with him two microscopes capable of scanning at the atomic scale: an Atomic Force Microscope with which we saw layers of graphite and a Scanning Tunnelling Microscope. His talk showed us images of human hair, minuscule cavities in teeth and even images of covalent bonds. He also illustrated several applications of Nanotechnology such as self-cleaning windows, releasing oil from chalk, and the use of silver in several antibiotic products such as plasters and deodorants. He has developed these high-quality microscopes with CambridgeNano at a fraction of the cost of normal machines capable of scanning at this scale.
