Selective electrochemical sensing of hemoglobin from blood of β-thalassemia major patients by tellurium nanowires-graphene oxide modified electrode

Hemoglobin is an important part of the biological system that is involved in the transportation of oxygen and carbon dioxide. Abnormal level of hemoglobin is associated with different diseases such as β-thalassemia and anemia. An electrochemical sensor based on graphene oxide-tellurium nanowires (TeNWs/GO) is developed for the first time for electrochemical sensing of hemoglobin (Hb). Sensing parameters such as concentration, pH, scan rate, and...
