Sensor platform using a horizontally oriented nanotube element
First Claim
1. An electric device, comprising:
- a flexible substrate;
a conductive article disposed on the flexible substrate, said article comprising a nanotube ribbon for providing a plurality of conductive pathways along the article, wherein said nanotube ribbon is flat and is of a substantially predetermined dimension in which the length and the width of said nanotube ribbon are significantly greater than the height of said nanotube ribbon; and
at least one electrode in electrical communication with at least a portion of the conductive article.

Abstract
Sensor platforms and methods of making them are described, and include platforms having horizontally oriented sensor elements comprising nanotubes or other nanostructures, such as nanowires. Under certain embodiments, a sensor element has an affinity for an analyte. Under certain embodiments, such a sensor element comprises one or more pristine nanotubes, and, under certain embodiments, it comprises derivatized or functionalized nanotubes. Under certain embodiments, a sensor is made by providing a support structure; providing a collection of nanotubes on the structure; defining a pattern within the nanotube collection; removing part of the collection so that a patterned collection remains to form a sensor element; and providing circuitry to electrically sense the sensor'"'"'s electrical characterization. Under certain embodiments, the sensor element comprises pre-derivatized or pre-functionalized nanotubes. Under certain embodiments, sensor material is derivatized or functionalized after provision on the structure or after patterning. Under certain embodiments, a large-scale array includes multiple sensors.
