Mmixed Self-assembled Monolayer on a Gold Surface (image) American Association for the Advancement of Science Share Print E-Mail Caption This is a false-colored atomic force micrograph of two types of molecules forming a mixed self-assembled monolayer on a gold surface. The two molecules differ in height by 0.2 nanometers, giving the appearance of ripples. This image was awarded first place in the photography category in the 2010 Science/NSF International Science & Engineering Visualization Challenge.
