The present invention relates to a method and apparatus for the synthesis of nanostructures using at least one solution providing at least one chemical element appropriate for the type of nanostructure, the method comprising the steps of: a) adding (admixing) a reducing agent to the at least one solution, b) bringing a suitable substrate into contact with the at least one solution before or after step a), c) forming nucleation growth sites on the substrate and d) maintaining the temperature at a suitable level for the growth of the nanostructures, characterized by the further steps of e) providing at least one space having at least one dimension in the micron range, e.g. in the range from 1 &#x3bc;m to 500 &#x3bc;m, adjacent a surface of the substrate, f) growing said nanostructures in said at least one space, g) periodically separating said nanostructures from the substrate and removing them.
