Figure 2.27 STMs and AFMs allow us to view images at the atomic level. (a) This STM image of a pure gold surface
shows individual atoms of gold arranged in columns. (b) This AFM image shows long, strand-like molecules of
nanocellulose, a laboratory-created substance derived from plant fibers. (credit a: modification of work by
