These are atomic force microscope images and chemical structures of a molecule before and after it reacts on a surface. The structures of the two major products of the reaction were unexpected ...

Contact mode is the simplest AFM mode conceptually and is the basis for a variety of other modes. It is the fastest of all topographic methods, capable of obtaining some of the highest resolution ...

That’s right. printing atomic force microscope images. The AFM image above is of a hydrogel, a network of polymers that’s mostly water, but has a huge number of crosslinked polymers.

Smaller images or more complex imaging modes will demand more stringent sample preparation ... It has to be 1-5 cm in diameter and less than 1 mm thick for optimal results. Conductive AFM must be done ...
