Carbon Nanotubes

Nanoelectronic detection allows one to harness the size and semiconductor characteristics of carbon nanotubes (CNTs) to detect practically any analyte electronically rather than optically. Stronger than steel, with electrical conductance greater than copper, CNTs enable the detection of a wide variety of biomolecules and gases on a single device with different chemistries. The size and structure of CNTs create a high surface-area-to-volume ratio and strong biomolecular affinity. With high specificity and reproducibility across a broad dynamic range, a large electronic response is evoked with the lowest concentration of analyte. Since only one single binding event is required to change the state of the entire nanotube, the technology is ideal for nanomolecular detection — with no assay crossreactivity. Coupling low-cost electronics, low power consumption, and the ability to integrate with any analyte, the Sensation™ technology platform offers performance two- to-four times that of competing POC technologies.

Ultra High Sensitivity

• Ballistic transport prevents signal dilution
• Coherent over longer distances (~µm) at room temperature
• Quantum mechanical properties
• Entire tube can be treated as a single molecule
• Theoretically allows detection of single binding events
