Electrochemical sensors based on 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 sensors due to their large surface area and superior electrochemical properties. In electrochemical sensors, 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 sensors, with the industry’s highest sensitivity.

Canatu carbon nanotubes offer a versatile material platform for electrochemical sensors 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 electrochemical 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.
