Electrochemical detection

Canatu carbon nanotubes offer a versatile, proven, and scalable material platform for electrochemical detection with the highest sensitivity in the industry.


Transforming electrochemical detection with the exceptionally sensitive Canatu CNT material

Canatu creates the most advanced carbon nanotubes tailored for highly engineered solutions, providing a versatile and proven material platform for electrochemical detection with the industry’s highest sensitivity. The exceptional sensitivity is attributed to the large surface-to-volume ratio and low background current of Canatu CNTs. Harnessing these distinctive properties enhances electrochemical detection, unlocking new possibilities for advanced diagnostics with the potential to revolutionize various industries.

With a proven track record of mass production in the automotive and semiconductor sectors, Canatu is now extending its expertise to transform medical diagnostics and beyond. The manufacturing process is compatible with roll-to-roll production, and successfully demonstrated at an industrial scale with the capacity to manufacture millions of sensors annually. Canatu’s electrochemical detection using CNTs holds the potential to deliver resilient, accurate, reliable, and cost-effective analysis in areas such as clinical diagnostics, environmental monitoring, industrial applications, and food & beverages.

Key benefits of Canatu CNT:

  • High surface area: larger contact with the analyte
  • Clean surfaces: better contact with both the analyte and the working electrode
  • High sensitivity even in complex matrices: better resistance against the contamination of the working electrode by large molecules like proteins
  • Excellent electrical properties: low background current and a high signal-to-noise ratio, enabling a lower detection limit

High sensitivity

Canatu CNT is the most sensitive electrochemical material when comparing options. Sensitivity is measured by delta Ep, which reports the potential difference between two peaks. A lower delta Ep indicates better sensitivity in the material. The theoretical minimum is 58mV for the Ferrocyanide reaction.

Electrochemical detection using Canatu CNT

Electrochemical detection enables rapid, selective, and quantitative chemical measurement. This method can utilize biorecognition elements, such as antibodies and enzymes, to modify electrodes for specific analyte. Biorecognition element interacts with the specific target analyte. Electrical signals are generated, and these signals are processed by an electronic system.

Carbon nanotubes are the most exciting materials used in electrochemical detection due to their large surface area and superior electrochemical properties. In electrochemical detection applications, this large surface area provides many binding sites, enhancing the capability to detect specific chemical analytes. Additionally, the unique structure of carbon nanomaterials offers distinct advantages. Unlike materials like gold and platinum, the carbon structure allows for a sturdy and reliable attachment of biorecognition elements, enabling effective functionalization across a broad range of applications.

Canatu CNT offers a versatile and proven material platform for electrochemical detection, with the industry’s highest sensitivity.

Canatu carbon nanotubes offer a versatile material platform for electrochemical detection with the industry’s highest sensitivity. Canatu uses a unique dry deposition method which yields high-purity CNTs, enabling a large contact with the analyte. The exceptional purity of Canatu CNT further facilitates the fabrication of electrochemical sensors with high sensitivity and stable low background currents, contributing to a high signal-to-noise ratio. Both the dry deposition and electrode patterning processes are fully compatible with roll-to-roll production and have been successfully demonstrated at an industrial scale.

Canatu’s dry deposition method yielding high-purity CNTs is fully compatible with roll-to-roll production, and successfully demonstrated at an industrial scale with capacity to produce millions of sensors annually.

Additionally, Canatu has highly developed expertise in customizing CNTs for application-specific needs. Both, the individual CNTs and the overall CNT network morphology can be tuned. For example, bundle size can be adjusted during CNT synthesis to optimize click chemistry, and carbon nanotubes can be purified to remove residual iron from the CNT synthesis. Our extensive in-house post-processing capabilities also extend to surface functionalization, enabling selectivity through immobilization of biorecognition elements. This positions Canatu CNT as a versatile material platform for electrochemical detection, particularly in the development of electrochemical biosensors and beyond.
