This paper tries to define the contents of master's programmes in Nanotechnology or Nanoengineering. This emerging technology holds large promises for industrial innovation and we need to prepare graduates properly as they will be confronted for most of their future careers with these new developments. The nano-world is a multidisciplinary world and the shortest way to a bad curriculum is filling it with a conglomerate of subjects from all disciplines. We should look for a philosophy and try to integrate disciplinary knowledge. Some of these questions are discussed and an implementation for a master's programme under the umbrella of Electrical Engineering is presented.
