A new approach to directly organize colloidal particles into patterned arrays using a nanostructured polymer template coated with polyelectrolyte multilayers is introduced. The topological template with both positive and negative charges provides a finely defined chemical nanopattern to guide selective deposition of colloidal particles onto the patterned surface upon Coulombic attraction (see figure).
