WebA vial with live diatoms in water was transferred into the AFM glovebox. A drop of water with diatoms was placed on a silicon substrate. After water evaporation the live diatom cells were measured using the AFM. The diatom samples were imaged with intact and separated frustules or the so-called valves. Reproduction among these organisms is asexual by binary fission, during which the diatom divides into two parts, producing two "new" diatoms with identical genes. Each new organism receives one of the two frustules – one larger, the other smaller – possessed by the parent, which is now called the epitheca; and is used to construct a second, smaller frustule, the hypotheca.
