Architectural control over large surface

Layer-by-Layer Adsorbed Films of Oppositely Charged Synthetic or Biological Polymers or Colloids Control of Layer Architecture Over Large Surface Areas... 

As mentioned earlier, there are a large variety of surface-modification techniques for achieving a desired surface architecture. Due to lack of sophisticated instrumental facilities, the researchers in the past had to compromise with techniques that were less surface-specific and offered little control over the process. However, with system automation, it is possible to develop surfaces with well-defined properties and morphologies, avoiding tedious processes.
