Here we describe a facile strategy of general applicability for controlling the immobilization of individual nanomoieties on nanopatterned surfaces with single-molecule control. We combine the ability of DNA nanostructures as programmable platforms, with a one-step Focused Ion Beam nanopatterning, to demonstrate the controlled immobilization of DNA origami functionalized with individual quantum dots (QDs) at predesigned positions on glass coverslips and silicon substrates. Remarkably, the platform developed is reusable after a simple cleaning process, and can be designed to display different geometrical arrangements.
