Dip-pen nanolithography is used to selectively modify the SiOx area between microfabricated electrodes. The modified surface is characterized by atomic force microscopy, X-ray photoelectron spectroscopy, force volume imaging, and adhesion maps. The functionalized complex architecture is used for the localization of DNA coated with magnetic nanoparticles. The strategy reported here can become the basis for the construction of a number of functional devices. The devices can utilize the unique recognition properties of the DNA and the magnetic properties of the nanoparticles that template them.
