摘要： A laminar structure upon a substrate is formed from a) a lattice layer comprising DNA (deoxyribonucleic acid) segments arranged to form cells of the lattice layer, and b), at least one nanoparticle being disposed within each cell of the lattice layer. The nanoparticles are preferably of substantially uniform diameter not exceeding 50 nanometers. A coating may be applied to adhere the the particles to the substrate and to maintain their substantially uniform spaced-apart relationship. The DNA lattice layer is fabricated using known automated synthetis methods, and is designed to contain specific nucleotide base sequences which cause the DNA to form an ordered array of openings, or lattice cells, by self-assembly. Self-assembly of the DNA lattice may be at an air-liquid interface, or in solution. A preferred embodiment is a magnetic storage medium in which the particles are magnetic particles with diameters in the range of 5-20 nm., the particles being organized in square information bits with each bit holding of 4, 9, 16, 25 etc. particles to produce areal information storage densities on the order of 1000 gigabits (one terabit) per square inch. The lattice of bits may be stabilized and protected by a deposited thin film, hard, abrasion-resistant coating.

摘要： A method and structure for making magnetite nanoparticle materials by mixing iron salt with alcohol, carboxylic acid and amine in an organic solvent and heating the mixture to 200–360 C is described. The size of the particles can be controlled either by changing the iron salt to acid/amine ratio or by coating small nanoparticles with more iron oxide. Magnetite nanoparticles in the size ranging from 2 nm to 20 nm with a narrow size distribution are obtained with the invention. The invention can be readily extended to other iron oxide based nanoparticle materials, including M Fe2O4 (M=Co, Ni, Cu, Zn, Cr, Ti, Ba, Mg) nanomaterials, and iron oxide coated nanoparticle materials. The invention also leads to the synthesis of iron sulfide based nanoparticle materials by replacing alcohol with thiol in the reaction mixture. The magnetite nanoparticles can be oxidized to γ-Fe2O3, or α-Fe2O3, or can be reduced to bcc-Fe nanoparticles, while iron oxide based materials can be used to make binary iron based metallic nanoparticles, such as CoFe, NiFe, and FeCoSmx nanoparticles.
