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.
