Adsorptive behavior of hemoglobin at a platinum electrode and its application to the determination of proteins

The adsorptive behavior of hemoglobin at a platinum electrode is investigat ed by employing cyclic voltammetry. On the basis of the investigations, an electrochemical method for the determination of hemoglobin is developed. Th is method is shown to be simple and sensitive. The detection limit can be a s low as 1.6 nmol/L. Since the working electrode does not need to be modifi ed and the experimental procedure is very simple, this method might be usef ul for protein determination in the future.
