I never ever thought that might be possible, but remarkably enough: if you look here, you can see before and after images of molecular transformations:  http://newscenter.lbl.gov/news-releases/2013/05/30/atom-by-atom/

Aldous Huxley took the title of his novel ‘Brave New World’ from the following quote from Shakespeare’s  the Tempest

O wonder!
How many goodly creatures are there here!
How beauteous mankind is! O brave new world
That has such people in’t!

O wonder!

The original reactant molecule, resting on a flat silver surface, is imaged both before and after the reaction, which occurs when the temperature exceeds 90 degrees Celsius. The two most common final products of the reaction are shown. The three-angstrom scale bars (an angstrom is a ten-billionth of a meter) indicate that both reactant and products are about a billionth of a meter across.
