microscopy

Pardon me while I go chemistry geek. It has recently come to my attention that Leo Gross and co-workers at IBM Research in Switzerland have developed a special atomic-force microscopy technique that can image actual molecules with enough resolution to “see” individual bonds and hydrogen atoms. Shown uppermost is a computer-generated model of the pentacene molecule, and below it, an actual image from the microscope. The microscope’s probe is tipped with a single molecule of carbon monoxide. Unbelievable.
