Electrochemical sensors based on Canatu CNT

Demonstrated >10x increased sensitivity in preliminary research (internal, unpublished data). Superior sensitivity is made possible by our patented dry deposition technology yielding the most advanced CNTs with incredibly extensive and pristine reaction surface area. 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 other materials used in electrochemical sensors, such as gold and platinum, carbon nanotubes’ three-dimensional carbon structure allows for a sturdy and reliable attachment of biorecognition elements, enabling effective functionalization across a broad range of applications.

The superior sensitivity is achieved through our patented dry deposition™ technology that allows us to produce CNTs with uniquely pristine and extensive surfaces.

Furthermore, the unique structure of CNTs offers distinct advantages for electrochemical sensors. In medical diagnostics, their three-dimensional carbon structure allows for sturdy and reliable attachment of biorecognition elements, enabling effective functionalization across a diverse range of applications.

The exceptional sensitivity unlocks unprecedented electrochemical detection capabilities for new assays. Our proprietary click chemistry provides a versatile platform technology for detecting any analyte of interest, including DNA mutations, pathogens, hormones, and drug molecules. This presents unique opportunity to detect severe diseases and infections in their earliest stages.

Click chemistry uses biorecognition elements, such as DNAs, antibodies, aptamers and enzymes to modify electrodes for specific target analytes. These elements interact with the target analyte, generating electrical signals that are then processed by an electronic system.

Canatu has the expertise and experience to produce tens of millions of sensors every year.

Canatu has the experience and expertise to produce tens of millions of sensors every year. Our patented dry deposition method and electrode patterning process are fully compatible with roll-to-roll production and have been successfully demonstrated on an industrial scale. We have been mass producing our sensors for multiple industries since 2015.

We also excel in customizing our CNTs to meet specific application requirements. With extensive in-house CNT post-processing capabilities, we can customize surface functionalization to immobilize biorecognition elements, enabling selectivity for specific target analytes. We can also adjust both individual CNTs and the overall CNT network morphology to suit specific requirements. For example, we can tune bundle size during CNT synthesis to optimize click chemistry, and purify CNTs to remove residual iron from the synthesis process to enhance sensitivity.
