Electrochemical redox signaling of hemoglobin in human whole blood and its relevance to anemia and thalassemia diagnosis†
Abstract
A highly redox active human whole blood–carbon nanomaterial modified electrode has been developed, which showed a redox peak (vs. Ag/AgCl) similar to that of hemoglobin (vs. Ag/AgCl) in red blood cells. Clinical relevance of this for direct electrochemical analysis of blood hemoglobin content (anemia) and thalassemia disease diagnosis was demonstrated.
