A method for generating magnetic nanostructures with dimensions ranging from several hundred nanometers to sub-100nm based upon dip-pen nanolithography (DPN) was presented. Magnetic iron oxide nanoparticles were prepared by the slow addition of an aqueous solution of ferrous chloride to an aqueous solution of ferric solution at room temperature. The magnetic particles were shown spherical in shape using transmission electron microscopy (TEM) and exhibited a size distribution from 4 to 16 nm.
