    Abstract: A method of stamping molecular patterns and/or devices based on the reversible self-assembly of molecules. In one embodiment, the method of forming a complement image of a master involves: providing a master having a first set of molecules (12) bound to a first substrate (14) to form a pattern; assembling a second set of molecules (16), having a reactive functional group (18) and an exposed functionality (28), on the first set (12) via bond formation; contacting the reactive functional group (18) with the surface of a second substrate (22), the reactive functional group (18) reacting with the surface of the second substrate (22) to form a bond between the second set of molecules (16) and the second substrate (22); contacting the remaining exposed surface of the second substrate (22) wit another group of molecules (24); breaking the bonds between the first set of molecules (12) and the second set of molecules (16), the second set of molecules (16) bound to the second substrate (22) forming the complement image (26) of the master. The master can be reused one or more times to form additional complement images.

    Abstract: An optical material system for nanopatterning is provided that includes one or more material systems having spectrally selective reversible and irreversible transitions by saturating one of the spectrally selective reversible transitions with an optical node retaining a single molecule in a configuration and exposing the single molecule to its spectrally irreversible transitions to form a pattern.

    Abstract: The present invention provides a method to eliminate undesired parallel conductive paths of nanogap devices for aqueous sensing. The method involves the electrical insulation of an electrode pair, except for the nanogap region wherein electrical response is measured. The magnitude of undesired ionic current in a measurement is reduced by two orders of magnitude. The process to accomplish the present invention is self-aligned and avoids fabrication complexity. The invention has a great potential in nanogap device applications.

    Abstract: A method for the synthesis of monodispersed, organic-monolayer coated, calcium-containing nanoparticles is presented. A biphasic liquid system comprises an aqueous phase of bare particles and an organic phase containing organic molecules with carboxylic acid end group is mixed. The carboxylic acid group binds to the surface of the calcium-containing particles and the particles are coated with a monolayer of organic molecules. The exposed surface of the coated particles is more hydrophobic than the surface of the bare particle and the particles are extracted to the organic phase. The process changes the geometry of the particles and decreases the size distribution in a population of particles.

    Abstract: An article has a surface, at least a portion of which has a local radius of curvature of about 1000 nm or less. For example, the article may be a nanoparticle or a surface, a portion of which has a roughness characterized by a radius of curvature of about 1000 nm or less . A monolayer coating disposed on the surface includes a plurality of ligands organized into ordered domains having a characteristic size of less than or about equal to 10 nm.
