Electrochemical biosensors
Electrochemical biosensors using Canatu carbon nanotubes offer industry-leading sensitivity and bring lab-level clinical analysis anywhere.
Electrochemical biosensors for point-of-care analysis
Electrochemical biosensor functions by converting biochemical events into electrical signals. At its core is the electrode, providing stable support for immobilizing biomolecules and facilitating electron movement. Carbon nanotubes stand out as ideal electrodes, thanks to their large surface area and electrical conductivity, resulting in high performance in terms of analytical sensitivity.
Canatu creates the most advanced carbon nanotubes through a unique dry deposition method. The inherently large specific surface area, high electrical conductivity, and tailorable surface chemistry make Canatu CNT an ideal electrode for electrochemical biosensors. Utilizing Canatu CNT, electrochemical biosensors achieve industry-leading sensitivity and high reproducibility.
- Sensitivity: Strong signal and low detection limit attributed to high electrical conductivity, a pristine CNT surface, and large contact area with the analyte
- Versatility: Ability to measure various substances across a broad range of fluidic samples, including sweat, saliva, blood, and urine
- Scalability: Proven mass production process with the capacity for manufacturing millions of sensors annually
Electrochemical biosensors bring the lab to anyone’s hand
Electrochemical biosensors bring the lab-level analysis virtually anywhere. Point-of-care electrochemical detection is on the rise, enabling rapid on-site detection of various biomarkers. These electrochemical biosensors hold great promise in transforming medical diagnostics, offering accurate and timely results, while making low-cost, easy-to-use, and accessible diagnostics possible.
Medical diagnostics
Medical diagnostics is rapidly transforming with an aging population and the rise in chronic and infectious diseases. Testing methods are shifting from centralized to point-of-care, enabling immediate results. Electrochemical biosensors hold a lot of potential to transform medical diagnostics by delivering high sensitivity, excellent accuracy, fast response, low cost, and easy handling. Using the most advanced carbon nanotubes as electrodes in electrochemical sensors provides distinct advantages, including the highest sensitivity in the market.

Canatu CNT’s sensitivity sets it apart and offers unprecedented opportunities
Electrochemical biosensors using Canatu CNT meet the World Health Organization’s ‘REASSURED’ criteria. These criteria, established by the WHO for an ideal test, aim to facilitate access to diagnostics and guide treatment in developing nations. REASSURED stands for Real-Time Connectivity, Ease of Specimen Collection, Affordable, Sensitive, Specific, User-Friendly, Rapid, Equipment Free, and Delivered.
Canatu CNT’s remarkable sensitivity sets it apart from other electrodes, offering unprecedented opportunities. The ability to measure and detect lower concentrations than ever before opens avenues for completely new applications, making early detection possible with potentially life-saving consequences.
Canatu is currently validating the feasibility of Canatu CNT-based electrochemical biosensors for various use cases, including but not limited to, therapeutic drug monitoring (Paracetamol, Tacrolimus), hormones (Testosterone, Dopamine, Serotonin), Drugs of Abuse (Fentanyl, Oxycodone, Morphine), antibiotics (Vancomycin), and bacteria / virus detection (E.Coli).
Electrochemical biosensor research
Our advancements in electrochemical biosensor solutions are progressing rapidly. A concrete proof of our capabilities in electrochemical detection is evidenced by a growing list of academic publications. Explore a summary of our recent research with the ecosystem partners and academia.
Electrochemical biosensors for detecting painkiller concentrations
For over four years, Canatu has collaborated with leading Finnish universities and Helsinki University Hospital to develop electrode strips for point-of-care measurements of painkiller concentrations. In this partnership, test strips capable of quantitatively detecting painkillers, including paracetamol and opioids, have been created. Given the widespread misuse of these medications, they are common causes of poisoning.
The developed test strips utilize the highly sensitive and repeatable Canatu CNT electrode platform, ensuring a high signal-to-noise ratio. These test strips have been validated in three early clinical studies, including the clinical validation of a test strip designed to measure paracetamol (acetaminophen) concentrations from small finger-prick blood samples.
