Our biosensor ODIN is based on an electrochemical approach utilizing differential pulse voltammetry (DPV). Our sensor uses screen-printed electrodes that provide a full three-electrode chemical cell within a tiny chip. The working electrode is then functionalized using graphene oxide. This ensures that the capture antibodies can be immobilized on the electrode. The patient sample can then be added to the functionalized electrode and the measurement can be done.
The results are presented as the concentration of an analyte in the sample. The concentration can be found, stored and shared with doctors or clinicians through our very user-friendly app.
