Abstract

An apparatus for detecting multiple analytes comprising an array of nanobiosensors, each comprising a biological entity immobilized onto carbon nanotubes, wherein a plurality of the nanobiosensors in the array have unique biological entities, wherein a first one of the plurality of nanobiosensors has a first biological entity immobilized onto carbon nanotubes, and wherein a second one of the plurality of nanobiosensors has a second biological entity immobilized onto carbon nanotubes, the first biological entity is unique relative to the second biological entity.

Claims

1. A method of detecting multiple analytes using an array of nanobiosensors, wherein a plurality of nanobiosensors in the array have unique biological entities immobilized onto carbon nanotubes.

2. The method as recited in claim 1, wherein a first one of the plurality of nanobiosensors has a first biological entity immobilized onto carbon nanotubes, and wherein a second one of the plurality of nanobiosensors has a second biological entity immobilized onto carbon nanotubes, the first biological entity is unique relative to the second biological entity.

3. The method as recited in claim 2, wherein each nanobiosensor includes a working electrode having a biological entity immobilized onto carbon nanotubes, a reference electrode, and a counter electrode.

4. The method as recited in claim 3, wherein the electrodes are connected to circuitry for scanning each of the nanobiosensors.

5. An apparatus for detecting multiple analytes comprising an array of nanobiosensors, each comprising a biological entity immobilized onto carbon nanotubes.

6. The apparatus as recited in claim 5, wherein a plurality of the nanobiosensors in the array have unique biological entities.

7. The apparatus as recited in claim 6, wherein a first one of the plurality of nanobiosensors has a first biological entity immobilized onto carbon nanotubes, and wherein a second one of the plurality of nanobiosensors has a second biological entity immobilized onto carbon nanotubes, the first biological entity is unique relative to the second biological entity.

8. The apparatus as recited in claim 7, wherein each nanobiosensor includes a working electrode having a biological entity immobilized onto carbon nanotubes, a reference electrode, and a counter electrode.

9. The apparatus as recited in claim 8, wherein the electrodes are connected to circuitry for scanning each of the nanobiosensors.

10. The apparatus as recited in claim 8, wherein the reference electrode is in close proximity of the individual working electrodes and arranged in an active matrix configuration.

11. The apparatus as recited in claim 8, wherein the multiple working electrodes configured in an active matrix can be driven simultaneously to detect multiple analytes.
