A new method for the fabrication of ordered arrays of small particles is reported here. A combination of microcontact printing of SAMs, surface‐templated self‐assembly, and confined crystallization has been used to produce 2D arrays of micro‐ and nanoparticles. The method allows highly accurate control over size distribution and spatial arrangement for a broad range of substrates, such as CdS on Au, as shown in the Figure.
