First Claim
1. A method of making a sensor, comprising:
- providing a support structure comprising a substrate;
providing a collection of at least one nanotube in contact with the support structure and oriented substantially non-parallel to a major surface of the substrate, so that at least a portion of the collection can act as a sensor element in contact with the support structure;
providing control circuitry to electrically sense the electrical characterization of the sensor element so that the presence of a corresponding analyte may be detected.

Abstract
Sensor platforms and methods of making them are described. A platform having a non-horizontally oriented sensor element comprising one or more nanostructures such as nanotubes is described. Under certain embodiments, a sensor element has or is made to have an affinity for an analyte. Under certain embodiments, such a sensor element comprises one or more pristine nanotubes. Under certain embodiments, the sensor element comprises derivatized or functionalized nanotubes. Under certain embodiments, a sensor is made by providing a support structure; providing one or more nanotubes on the structure to provide material for a sensor element; and providing circuitry to electrically sense the sensor element'"'"'s electrical characterization. Under certain embodiments, the sensor element comprises pre-derivatized or pre-functionalized nanotubes. Under other embodiments, sensor material is derivatized or functionalized after provision on the structure or after patterning. Under certain embodiments, a large-scale array of sensor platforms includes a plurality of sensor elements.
