Regular arrays of metallic nanoparticles are formed by these authors using a novel technique involving electron‐beam induced cluster formation in the transmission electron microscope (TEM). Nucleation is initiated in the cavities between crystalline bacterial surface layers deposited on a solid support, as schematically illustrated in the Figure.
