First Claim
1. A system, comprising:
- a sample exposure region comprising a reaction entity associated with a nanoscale wire; and
a first species and a second species different from the first species, each within the sample exposure region, wherein each of the first and second species is able to interact with the reaction entity or to affect interaction of the reaction entity with the other species.

Abstract
The present invention generally relates to nanoscale wires for use in determining analytes suspected to be present in a sample, especially in connection with determining information about a sample containing, or suspected of containing, two or more analytes. For example, the invention can involve a competitive, uncompetitive, or non-competitive binding assay including a nanoscale wire to a sample containing a species able to interact with the retain entity to produce a product, where the sample also contains or is suspected of containing a second species able to interact with the reaction entity to prevent production of the product resulting from interaction of the first species and the reaction entity. Based upon determination of production of the product, determination of the second species in the sample can be made. In one set of embodiments, nanoscale wires can be used that have been functionalized at their surface, and/or in close proximity to their surface, for example, by immobilizing a protein or an enzyme relative to the nanoscale wire. Functionalization may permit interaction of the nanoscale wire with various analytes, and such interaction may induce a determinable change in a property of the nanoscale wire. Determination of two or more analytes, o one analyte and the suspected presence of another analyte can involve, for example, binding species to a protein or an enzyme immobilized relative to the nanoscale wire. Other aspects of the invention include assays, sensors, detectors, and/or other devices that include functionalized nanoscale wires, methods of making and/or using functionalized nanoscale wires (for example, in drug screening or high throughput screening) and the like.
