A method according to one aspect of the invention includes dispensing a slurry onto a substrate wherein the slurry includes a first plurality of elements, each of which is designed to mate with a receptor region on said substrate and each of which comprises a functional element, and wherein the slurry also includes a second plurality of elements which are not designed to mate with receptor regions on the substrate. Typically, these second plurality of elements help movement of the first plurality of elements.

  • Patent number: 7311943
    Abstract: A self-replicating monolayer system employing polymerization of monomers or nanoparticle ensembles on a defined template provides a method for synthesis of two-dimensional single molecule polymers. Systems of self-replicating monolayers may be used as templates for the growth of inorganic colloids. A preferred embodiment is a SAM-based replication, wherein an initial monolayer is patterned and used as a template for self-assembly of a second monolayer by molecular recognition. Once the second monolayer has formed, it is polymerized in place and the two monolayers are separated to form a replicate. Both monolayers may then function as templates for monolayer assemblies. A generic self-replicating monomer unit suitable for use in one embodiment comprises a polymerizable moiety attached by methylene repeats to a recognition element and an ending unit that will not interfere with the chosen recognition chemistry.

  • Patent number: 7312095
    Abstract: An electronic system for selectively detecting and identifying a plurality of chemical species, which comprises an array of nanostructure sensing devices, is disclosed. Within the array, there are at least two different selectivities for sensing among the nanostructure sensing devices. Methods for fabricating the electronic system are also disclosed. The methods involve modifying nanostructures within the devices to have different selectivity for sensing chemical species. Modification can involve chemical, electrochemical, and self-limiting point defect reactions. Reactants for these reactions can be supplied using a bath method or a chemical jet method. Methods for using the arrays of nanostructure sensing devices to detect and identify a plurality of chemical species are also provided.
