Touching the surface : DNA‐labeled gold nanoparticles can be removed from a planar substrate by using a heterogeneous DNA displacement reaction. An advantage of using a planar substrate is that quantitative and kinetic studies of the displacement process could be achieved. This provides a fascinating way to control nanomaterials and to develop novel nanodevices on planar substrates by combining DNA hybridization and displacement reactions.
