Colloidal monolayers with high order and increased complexity beyond plain hexagonal packing geometries are useful for 2D templating of surface nanostructures and lithographic applications. On page 3064, Clemens K. Weiss and co-workers present binary colloidal monolayers that are prepared using a Langmuir trough. The stoichiometric composition of the large and small particles at the interface can be precisely adjusted to gain control over the occupation of the interstitial sites with small colloids.
