Manipulation of molecules with nanoscale accuracy is important in nanotechnology. In the novel process reported here, electrostatic interactions direct the deposition of polycationic Mn12 single-molecule magnets into a predefined region of a 1 cm2 silicon chip with 40 nm accuracy (see figure). The process is based on the integration of local oxidation nanolithography with surface functionalization of the Si substrate.
