Methods for using the arrays of nanostructure sensing devices to detect and identify a plurality of chemical species are also provided.Type: GrantFiled: March 15, 2002Date of Patent: December 25, 2007Assignee: Nanomix, Inc.Inventors: Jean-Christophe P.

Patent number: 7311943Abstract: 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.Type: GrantFiled: July 17, 2003Date of Patent: December 25, 2007Assignee: Massachusetts Institute of TechnologyInventors: Joseph M.
