Patent ID: 8920619

Claim:
A sensing device, comprising: a substrate; and four carbon nanotube arrays arranged on the substrate, each one of said four carbon nanotube arrays individually including: a plurality of carbon nanotube rows, each row including a plurality of carbon nanotubes, each carbon nanotube in a respective row being directly bound at one end to the substrate, first and second contiguous array sections, the first array section including at least two rows of the plurality of carbon nanotube rows, and the second array section including at least one row of the plurality of carbon nanotube rows, the carbon nanotubes within an array section having the same functionality, each array section being configured to be individually addressable, such that all carbon nanotubes within the array section are addressable via a common connection line, and each array section being configured to sense a corresponding analyte when exposed to a fluid solution containing one or more analytes.
